Move over, Geek Squad. I've got an idea.

Offer short-notice support sessions for small businesses and home users, helping out with hardware and software issues.

Exmaple: Joe Blow, small engine repair shop owner, has a computer in the shop. He is in the process of making up new price sheets in Microsoft Word, but can't figure out how to align the tabs on the right margin. Joe calls me up, explains the situation, I hop in my (t)rusty ride, drive over to his shop, assess the situation, then show him step-by-step how to do what he's wanting. During the process, I jot down notes, and have him do likewise, so in the future he can pull those notes out and do the task again. The session takes about 45 minutes, so I charge him for an hour. He tips me, asks for cards to hand out to friends and family, and I'm on my way.
