re: Buying into a business

Two thousand dollars for 10% puts a valuation on the "business" of $20k. What does he need the money for? Because that's not a lot of money. Is he more interested in your time?

It's going to cost close to half that just to get the paperwork in order.

Then sell this business in a year the he has valued at $20k? For how much?

Are you just funding? Will you participate? No offense, but this whole thing sounds very odd. That's probably the nicest way to say it.
