Worksheet rule: core software selects in-house; marketing selects freelancers below $6,000, otherwise agencies. Validate real scope, costs and capability separately.
Authored scenario: the recommendation, costs and coverage are assumptions, not supplier evidence. Adjust inputs and compare dated quotes.
| Cost Factor (Monthly) | Solo In-House Dev | Specialized Agency | Freelance Pool |
|---|---|---|---|
| Base Compensation / Fee | $11,250 | $12,000 | $8,500 |
| Assumed Benefits/Taxes (23%) | $2,587 | $0 (Assumed included) | $0 (Assumed; verify status) |

| Internal Management Overhead | $1,400 (Engineering Lead) | $0 (Assumed included) | $2,168 (Residual) |
| Modeled Monthly Total | $16,087 / mo | $12,000 / mo | $10,950 / mo |
1. Hard Performance Audits
Don't trust marketing screenshots. Request live production URLs and run independent benchmarks:
- ✓ Core Web Vitals: Check field LCP ≤ 2.5s, INP ≤ 200ms and CLS ≤ 0.1 at the 75th percentile.
- ✓ Repeatable lab diagnosis: Record device/network conditions and compare repeated runs; a grade does not establish code quality.
- ✓ Mobile usability: Test actual controls, keyboard access and layout stability; do not infer accessibility from a performance score.
2. Client & Code Scrutiny
Unfiltered evaluation steps before committing to any 3+ month retainer:
- ✓ Direct Customer Inquiries: Ask past B2B clients about sprint adherence and SLA responsiveness.
- ✓ Code Ownership & CI/CD: Agree on repository access, ownership, test evidence and handover; inspect dependencies and exit constraints.
- ✓ Security Hygiene: Select applicable OWASP ASVS requirements and request evidence; headers alone do not establish compliance.
3. Recommended Paid Pilot Task
Use a small, agreed paid pilot with explicit acceptance criteria and reviewable evidence.
Illustrative budget: $750 - $1,500 | Illustrative window: 3 - 5 business days | Agree a rubric before work.
