I mean what exactly are you going to do yourself? Call the shots?
You ask for a development lead, and you ask for the same person to finance the project's development? Are you that dumb to not understand that developers who are looking for jobs here and will probably be PMing you right away are not rich at all to be able to become venture capitalist whales themselves. That is exactly why they are here looking for small time jobs.
First point, declare a budget for the development. Next start the development and separately start for fundraising attempts be it private or public. Keep it professional like that, have we forgotten basic business etiquette now?
