In Atlanta, we get $75 minimum trip charge although estimates are free unless we fix the problem at the estimate. Most job are on a bid or fixed cost, so we only do hourly rate work on large imposible to bid jobs. Averages $50 per manhour in bulk or $75 per hour for one man. We are on the low end in our area, but I have to sleep and refuse to overcharge. My costs are more than what some of you are charging, but if you can make it work and are happy I guess that's what counts. Good Luck.
