I make a little pocket change doing some repair work here and there. I charge very little, actually, since it is family and coworkers. Many times I do it for free.
Here lately I have been swamped, though. In the last two weeks I have worked on three laptops, three desktops, and have another coming this evening to drop one off. I haven't made a dime off of any of them, and I doubt I will charge the guy coming tonight.
Yeah, I'm pretty soft-hearted. Even when I do charge I let them pay what they want to pay me. I have gotten from $20 to $80 for cleaning up a computer (spyware and stuff), which the vast majority of what is brought to me.
