I have an incredible full-time Filipino virtual assistant for my mainstream sites that I hired through
http://www.virtualstafffinder.com/. You're going to have to pay them $400 to find you good candidates that you give the final interviews to and pick from, but it's well worth it as the candidates they give you actually have experience in what you ask for, be it content creation, design, etc. The only problem with this company is I don't know if they place for adult, so you would have to ask them.
But if you are just looking for really simple grunt work like tube uploads you should have no problem finding that from sites like Freelancer, Odesk (which I think doesn't allow adult jobs but you can work around that), Digital Point, etc.
