Has anyone here done any consulting for desktop computer repair? I'm being asked to help someone fix some problems with their mac. From a technical standpoint, this is absolutely no problem, I've got some good ideas already as to what the problem is, and how to fix it. But I don't know what to charge. I used to do unix consulting work, but I don't think charging my old consulting rate to this woman is very fair, nor appropriate for the work that I'm going to be doing. Any ideas?
