Well, to be frank, if you want 1,000 MRR, you're going to need to put in the work. You seem averse to the 'upfront work' part of things, but money isn't free. Well, unless you're already rich.
There's a big difference between having an MVP done in 3 or 4 months vs. in a year when you're the only person designing, developing, marketing and supporting it. When I take too long to ship something, I get discouraged and bored of the project.
A better way to put it: I'm having trouble thinking of anything I could ship a v1 in 4 months.
Not complaining, just sharing my experience as I think other HNrs may be in a similar situation.
Dentists? no shows are a problem for them. Same for hotels. Car repair? is it easy to find one close to you?
Find someone you can have easy access to: you'll have to talk. Talk to your friends. Learn to HEAR when they tell you what's their pain.
