I read in another post that they charge .85 per linear foot for edging. I went out to do an estimate and measures this potential customers sidewalk and driveway and it came out to be 400 ft. and his property is less than 1/2 acre. If i do the math right (400 X .85), then that is $340!!!! The edging with a gas powered edger would only take about 20 minutes. $340 seems WAYYYY HIGH!!!!!!! Am i doing something wrong??? Thank you for your advice.
