There's places where minimum wage is 2 bucks a day... problem is to find a worker that has very good English ;)
Depending on the kind of tasks and if it could indeed be a part time position, I might have someone for you, hit me up
EDIT: Regarding freelancer places, you can check
www.getafreelancer.com, there's a lot of people from south america, and asia there, and the ones I've worked with have turned out great. And everybody loves something steady.
