I'm lately did some businesses， which were I outsourced some art jobs and hired a few artists to do it as their part-time or freelance jobs. I'm now interested in getting some foreign artists to coorperate with me. Most of the jobs I'll supply is $4 per hour, so I think they can only attract people who are living in a place of a living standard matchable to this salary. I think I can inform the right people in forums of conceptart.org, as I see there are artists almost from every country. But My biggest question is what qualifications should I possess and what kind of contract should we seal, if I'm going to do it very formally?
And another point, is it valid in every country that an employer could require a test from a candidate before doing the real works, which won't be paid?
Thanks in advance.
