Although I was able to find the artist I needed and working with him was great, it was not without going through HELL with Freelancer.com. This company has NO centralized customer service. NO phone number that is viable for anyone who lives in the U.S. to call. When I had an issue to resolve it took them so long to resolve it and in the meantime they locked up my Freelancer account and the account of the artist I was hiring. If it wasn't for the artist I would report this site but I know that this is a way for him to get work.
But be warned, if you work with Freelancer and you need customer assistance, be prepared to wait 2-3 weeks to have your problem resolved.
If you're in the U.S., it's better to find someone local or go direct to the artist or service provider.
