listen, there are guys in india and pakistan who do this kind of stuff...they sell nonsense (such as paperclips and gmail accounts) on ebay to rack up a decent score. after a few months the links to the items (ie paperclips) that were sold expire so your customers will have no way of knowing which items the positive feedback was from. but you'll get an account with 100% positive feedback.
anyways, i'm sure its illegal but who's asking. go to getafreelancer and put an ad stating what you want and see what kind of response you get.
