Computer rentals

Computer rentals

Are there any legitimate companies that do computer rentals? I'm seriously considering doing online tutoring, but tutor.com requires a PC, and I'm a Mac girl. I don't have a problem ponying up for a PC if the income is going to be good, but I'm hesitant about the whole "buy a PC and hope that it works" thing. Edit: No, I don't have an Intel Mac. Yes, I need to run specific Windows programs. That combination is the crux of the problem.
