What MRM said. If you're that busy, raise your rates.

FWIW, the only Porsche shop I ever trusted when I was in VA told me they make most of their money on fluid changes and valve adjustments. I knew that made me one of their least valuable customers, as I only came to them when I had a real problem I couldn't tackle like OBDII diagnostics, emissions and fuel injection issues. When they saw me coming, they knew they'd get nothing more than hourly billing and asked me how long I wanted them to work on something before calling it quits in case the answer wasn't apparent by then. In fact, I only asked them to do diagnostics for me and then I took the car home and fixed whatever they said was wrong. Hey, it's not my fault their main guy liked to talk with me on the phone and explain every little thing he had done and was thinking. I sure referred them a lot of work. But I just like DIY'ing too much, so they only got the hard stuff from me.
