  Work autonomously and use web search. Deliver, as separate files or clearly separated sections:
  1. A demand check: 10 real signals that people in my area/market pay for this today (links to competitors, reviews, job posts, forum threads).
  2. The 5 strongest local/online competitors with pricing, positioning and one weakness each.
  3. My offer: a specific niche, 3 packages with prices, and why a customer picks me.
  4. A one-page business plan with a startup budget table under my budget.
  5. A 30-day launch checklist, day by day, with the first paying customer as the goal by day 14.
  6. Copy for a one-page website and 3 outreach messages.
  Ask me at most 3 clarifying questions first, then go. Flag anything that needs a license, permit or insurance where I live.
