Most MVPs take 6–12 weeks with agencies or 2–3 months hiring full-time. Fixed scope and the same stack every time. That's why it takes days, not months.

Every project starts with the scope in writing. No hourly billing.
Typical agency quote for similar scope: $3,000–$8,000 with 6–12 week timeline. Upwork freelancer with my experience: $40–$80/hour × 40–80 hours = $1,600–$6,400.
Fixed price: The number we agree on is the number you pay.
You own everything: Code, repo and every account.
7 days of bug fixes: After launch, at no extra cost.
