My computer teacher hired myself and a friend of mine the summer we were headed into the 9th grade to clean all the computers in the school district. Seven separate schools over a one or two week period where we cleaned monitors, removed dust (and boy was there dust), and made sure they all turned back on when we were done.
I made about $900 total, but I also gained a love of computers. That job is one of the reasons I write software today.
