Does anyone have any estimating formats, formulas or spreadsheets that they use. Today a custmer asked me to trim a 100 ft hedge down by 3 ft and in by 4ft. I usually don't estimate these type of job very well. I estimate the time it would take me to do the work by myself to get the amount of man hrs needed. The problem is when I send a crew to do the work it is not completed in the amount of hrs I projected. I could use some advice.
