I am lucky that my friend who i trust is living in same country (same city even) and we teamed up to make some indie games. So for now I do not have headache of international team members. At some point (when we get some funds for game) we hire artists, pay them for work and that is it. We have luxury of us both being coders, so there is no need of giving source files to anybody. Artists can work with compiled game taken from flightest.
