Step 1: Build Your Prompt Library

Your prompts are your product. A mediocre prompt produces a mediocre resume. Invest significant time in perfecting them.

Prompt 1: Information Extraction

“Analyze this resume and job description. Extract: (1) All skills mentioned in the job description, (2) Skills the candidate has that match, (3) Skills gaps, (4) Key accomplishments that can be reframed for this role, (5) Industry-specific terminology to include. Present as a structured analysis.”

Prompt 2: Resume Rewrite

“Rewrite this resume for a [Job Title] position. Requirements: (1) Reverse-chronological format, (2) Each bullet starts with an action verb and includes a quantifiable result where possible, (3) Include these keywords naturally: [keyword list], (4) Maximum 2 pages, (5) 3-line professional summary positioning the candidate as an ideal fit, (6) Optimize for ATS: standard headers, no tables, consistent dates. Do not fabricate experience.”

Prompt 3: Cover Letter

“Write a cover letter for this resume applying to [Job Title] at [Company]. Requirements: (1) Opening hooks with a specific insight about the role, (2) Middle connects 2-3 accomplishments to job requirements, (3) Closing with clear call to action, (4) Professional but not stiff, (5) Under 350 words, (6) Do not repeat the resume — add narrative context.”

Prompt 4: LinkedIn Optimization

“Optimize this LinkedIn profile for [Job Title] in [Industry]. Provide: (1) Headline with title, value prop, keywords (under 120 chars), (2) About section telling a career story with keywords (under 2,000 chars), (3) 5 skills to add, (4) Specific improvements for headline and summary.”

Prompt 5: Interview Prep Questions

“Generate 15 interview questions for a [Job Title] position at [Company Type], plus suggested answer frameworks based on this candidate’s experience. Include: 5 behavioral questions (STAR format), 5 technical questions, 5 situational questions. For each, provide a 2-sentence answer framework.”

Test Every Prompt

Test each prompt with your own resume or a friend’s. Refine until the output quality is consistently strong. Save all prompts in your Notion Prompt Library.

CHECK-IN: Step 1 Complete

1. All 5 core prompts written and tested
2. Output quality is consistently professional
3. Prompts saved in Notion Prompt Library

Step 2: Create Your Resume Templates

Design 3 Resume Templates in Canva

Go to canva.com. Search “resume template.” Select 3 professional templates:

1. Clean Professional — Single-column, traditional layout. For corporate roles.
2. Modern Two-Column — Skills sidebar + experience column. For tech and creative roles.
3. Executive — Substantial layout with space for extensive experience. For senior roles.

Customize each template: replace placeholder content with merge fields (e.g., [NAME], [TITLE], [SUMMARY], [EXPERIENCE], [EDUCATION], [SKILLS]). This makes it easy to swap in AI-generated content quickly.

Create a Plain Text (ATS) Version

Create a Google Docs template with: standard section headers (Professional Summary, Experience, Education, Skills), no tables or columns, consistent date formatting (Month Year), and no graphics. This is the ATS-optimized version that every client needs alongside the designed version.

CHECK-IN: Step 2 Complete

1. 3 designed resume templates in Canva
2. 1 plain text ATS template in Google Docs
3. All templates use merge fields for easy customization

Step 3: Set Up Your Service Delivery Workflow

The Client Intake Form

Create a Google Form or Typeform collecting:

• Full name and email
• Current resume (file upload)
• Target job title
• Target industry
• Link to target job description (if they have one)
• Career level (Entry, Mid, Senior, Executive)
• Package selection (Basic $49, Professional $129, Executive $297)

The Delivery Process

For each client:

1. Receive intake form — Save to Notion client database
2. Upload resume to ChatGPT — Run Prompt 1 (Information Extraction)
3. Run Prompt 2 (Resume Rewrite) using extracted analysis
4. If Professional/Executive package: Run Prompts 3 and 4 (Cover Letter + LinkedIn)
5. If Executive package: Run Prompt 5 (Interview Prep) + schedule a 30-minute coaching call
6. Copy output into the appropriate Canva template or Google Doc
7. Review and edit — This is critical. AI output needs human review for accuracy, tone, and personalization
8. Export as PDF (designed version) and .docx (ATS version)
9. Email deliverables to the client within the promised timeframe
10. Follow up after 3 days for feedback and after 30 days for outcome tracking

CHECK-IN: Step 3 Complete

1. Intake form created and tested
2. Delivery process documented step by step
3. Quality review checklist created

Step 4: Build Your Sales Funnel

The Free Resume Review Lead Magnet

Create a simple Google Form: “Free AI Resume Review.” Ask for: current resume (upload), target job title, target industry.

Process: Upload to ChatGPT, run this prompt:

“Review this resume for a [Job Title] position. Provide: (1) ATS compatibility score (1-10), (2) 3 missing keywords for this role, (3) 2 bullet points that need impact framing, (4) 1 format issue, (5) One specific rewrite example showing before/after. Be specific and actionable.”

Email the 5-point review for free. At the bottom, offer: “Want me to implement all improvements and deliver a fully optimized resume within 24 hours? $49.”

Set Up Your Gumroad Listing

Go to gumroad.com. Create a product listing for each package:

• Basic Resume ($49) — Resume rewrite + ATS optimization
• Professional Package ($129) — Resume + cover letter + LinkedIn optimization
• Executive Package ($297) — Everything + 3 targeted versions + interview prep + coaching call

Write compelling product descriptions that focus on outcomes: “Land 3x more interviews with an ATS-optimized resume” rather than “Get a new resume.”

CHECK-IN: Step 4 Complete

1. Free resume review lead magnet live
2. Gumroad listings created for all 3 packages
3. Payment processing connected via Stripe

Step 5: Automate the Delivery Pipeline

Create a Make.com Scenario

Trigger: New Gumroad sale → Webhook

Module 1: Notion — Create Page — Create a client page in your Notion database with: name, email, package type, order date, due date, status.

Module 2: Gmail — Send Email — Automated confirmation: “Hi [Name], your order is confirmed! I’ll deliver your [Package] within [timeframe]. Please fill out this quick form so I can tailor everything to your goals: [Intake Form Link]”

Module 3: Notion — Update Status — When intake form is submitted, update status to “In Progress.”

This saves you 10-15 minutes per client and ensures nothing falls through the cracks.

CHECK-IN: Step 5 Complete

1. Make scenario creates Notion page on new sale
2. Confirmation email sent automatically
3. Status tracking works end to end

Step 6: Scale with Templates and Team

Build Industry-Specific Prompt Libraries

After 20 clients, you will notice patterns by industry. Create specialized prompts for:

• Tech/Engineering — Emphasize technical stack, system design, and impact metrics
• Healthcare — Highlight patient outcomes, certifications, and compliance
• Finance — Focus on deal size, portfolio performance, and regulatory expertise
• Marketing — Showcase campaign metrics, brand growth, and creative strategy
• Education — Frame curriculum impact, student outcomes, and pedagogical innovation

Each specialized prompt reduces delivery time by 40% because the AI does not need to infer industry conventions.

Hire a Review Editor

At 30+ orders per month, hire a part-time editor ($15-25/hour) to handle the human review step (Step 7 in the delivery process). You focus on prompt optimization, sales, and high-value executive packages. The editor handles quality control on basic and professional packages.

Launch a Subscription Tier

Offer “Career Accelerator” at $29/month: monthly resume updates for each new application, new cover letters, and priority interview prep. 50 subscribers = $1,450/month in recurring revenue.
