I brought up widening a chain link fence gate to a customer so that I could get a bigger mower in the backyard. He said that he would like me to price it out. I have never done this before and would be willing to do it for cost. Anyone have any idea of cost and time to do something like this? Would you charge your regular hourly rate if you knew that this customer would be with you for several years and it would save you a headache every week by not having to bring the 36" mower?
