Find a useful business idea inside an impossible constraint

I have [SKILL OR RESOURCE] and these real limits: [TIME], [BUDGET], [LOCATION OR ACCESS], [NON-NEGOTIABLE]. Generate five unusual service or product ideas that fit, each grounded in a specific customer task rather than an AI buzzword.

For each idea give the customer, painful moment, smallest deliverable, what must be done by a human, the first ten potential customer conversations and an honest reason it might fail. Choose the two most testable options and design a seven-day experiment costing no more than [BUDGET]. Include a stop criterion and one possible pivot. Separate desk assumptions from evidence collected in the real world.

No invented demand numbers, fake testimonials, guaranteed income or paid marketing required. Prefer surprising combinations that are still operationally plausible.
