If want people to help you, you should probably post pictures or at least a story that you have come up with. Now I have no idea how experienced you are in making games, or if you have none at all (which is my guess because this is your first post), but if it is, you should start small, make a small level and get an idea of how things work in the engine, and then keep trying bigger things. I am not trying to bash you or anything, but you really won't get people to help you otherwise.

Hope this helps,

P.S. you should also say how much you are going to pay for people to help you.
