If you're willing to make a quick 1 page bill of sale detailing that the sale is final, and that you will not charge back the card... You could put this on a Credit Card and he shouldn't have a problem with it. He can get a free merchant account from a dozen or so online companies and would have his cash anywhere between 3-30 days depending on which company he chose to go with. If you're serious, educated on the fairly painless process, and he is willing to listen, you could easily put that on a card and have it be safe for the seller. =]
