For starters: wrong section. Also, have fun finding people that will work unpaid; pretty much nobody does this, and with good reason: time equals money. When people spend time coding for you or animating your models, they'd expect money in return, since when time goes you can't really get it back - money is the easiest currency to pay it back with, or at least give them some gift of some sort (Steam cards, some models worth $$$, etc)
