I try to stay very local, 10 miles or so. But as the season slips away I am looking for more work. I received a call for a job that is 30 miles away so 60 round trip and no other work in that area. It is seems that money is not an issue with this client (they say just send the bill) but they say that they have paid $50 for the mow in the past. Should I charge $70 just because of fuel cost? I know I should also account for my time driving but I actually have nothing else to do. Thoughts?
