Recently, I sold a United Caribbean and brought it to set it up at the guy's house. Turns out he had about 15 other machines in his basement, many of which need little things looked at and he asked me if I could have a look at one of them. So up until now, any machine I've worked on has either been in my personal collection or one I bought to flip. I've never charged to work on someone else's machine. I know this may be a loaded question but what is a fair rate? If I weren't underemployed at the moment, I probably wouldn't bother, but money is tight.
The job at hand would be diagnosing and/or replacing a sound board and a stuck flipper on a Gottlieb Genie
