We have the Services board here where you can post something like you are looking for devs to help you out building your project. But just be cautious though as there might be newbies pretending to be a good developer, so just filter all the applicants.

Any budget though? usually great coders requires high pay, so you have to look at that as well. I guess it better you build your own team, at least you can have total control of everything, as the mover behind the project, best of luck.
