I'm assuming that you'll need to replace part number 1 in the pic. It's about $42 from Honda. The motor is not that badly priced either. It's about $100. I've seen them in the several hundred dollar range before. If new isn't in the budget, a bone yard may be your best bet for parts.

Here's directions on how to remove the regulator for the window. I won't lie to you, it's going to be a pain in the ass, you'll get frustrated and probably cut your hands to shit on the sheet metal. Just take your time and it should be no problem.
