Is it possible to sell people under legal age on ebay?

If you were to go to a poor country and adopt a child (legally) and pay the parents money (let's say $100USD) and then put them in the care of someone else (via ebay) for a certain amount of money (let's say $10,000USD) and then eventually give them legal custody through adoption processes. NOTE: When you answer don't talk about the freakn' ethics just the legality.
