Also, Walmart was founded because Sam Walton's wife was adamant she wanted to live in a small town. He loved her. He respected her wishes. He became ridiculously wealthy. Get over the idea that real businesses start in the big city.
Best of luck.
My suggestions in order:
1. Build a working prototype first. Either do it yourself or get a freelance developer to do it if you cannot do it yourself.
2. Market. Talk to everyone you know. Go online. Start writing about the product. Buy adwords if you have to. Put a simple landing page.
3. Attend local meetups if possible. This is usually a hit or a miss but it can never hurt. Search for meetups within the business idea that you have. Again, this will be like finding a needle in a haystack but you may find that needle.
Oh, repeat 1-3 infinitely until...
Have you defined exactly what sort of help you need? If you can get clear on that, then it's a relatively easy process to zero-in on where that sort individual hangs-out either online or in-person. Say there's a meet-up in major hub city. It's worth making a special trip to attend. You might need to have 100+ conversations till you find the right person.
Speak to your target market and get them hyped about your product. If you can get them to pre-order then even better.
Don't think you know exactly what people want because you're most likely going to be wrong and will waste so much of your time and money.
