teachstreet.com attracted funding from Madrona (a pretty solid VC firm) as well as Dave McClure, I think. Same thing, I suppose.

Bounce around craigslist for a bit and see how many people are buying and selling lessons. It's a big business.

A good percentage of those are scams, eg: "Spanish tutor wanted." They advertise for some lessons from someone likely to be semi-desperate but with a bank account. Then they kite a check from a stolen bank account for twice the amount to the sucker, and ask them to pass the rest to the "nanny". The child of course never appears.. and they say "oh, keep the money." They play on greed and fear to rope the sucker into doing the most dangerous part of the fraud and to keep quiet later.

Seriously. Answer ten teacher wanted ads and 2-3 will be scams of some sort.
