I'm looking to hire a studio or a group of programmers to design a game, but I'm not sure how to pay them that is both fair to them and safe for me. Is there a common method that I'm un-aware of? Do I escrow the whole amount? Do I give % of total amount up front and payments there after? Also, should I get a lawyer to copy right and set up a non-disclosure agreements before even speaking to anyone? I'm new hear, so hoping to soak some knowledge that I can't dredge up myself on these awesome forums.
