How do you guys estimate costs for linear trimming/edging? I'm guessing it's similar to area, meaning we average a mile @ 5,280 ft and divide it into the length we're cutting. Correct? If this is the case, do we average how far we (the operator) can edge in a certain timeframe? I have a job of 1,915 linear feet (Think curb guttering here) + basic lawn maintenance. I figure the estimate I give will have to be based on experience, correct? Or is there a tried-true method you guys use? I don't want to guesstimate and eat it. Thanks ahead of time for the responses.
