Hi Mehek,
If you dont have money and really believe in your project and want some good developer/s, you need to follow below IMHO:
1-) Make a concrete business plan, specify your milestones , requirements etc.
2-) Open a Crowdfunding campaign in kickstarter or equivalent CF sites. Do not hesitate to express your project in a rough detail. If CF campaign is succesfully funded, then you can have confidence that your project can go somewhere
3-) If you get enough money then hire some developer/s for your project
4-) Finish your project
If you aply above steps succesfully , maybe you can do what you have in your mind. Otherwise, its very very hard to get any developer for your project.
your lack to show you can do research means you shouldnt be a business owner, plus hearing your idea, is not all that great, your just a poor man having a get rich dream.
