Got a call to do string trimming only. Older couple. Property is edged by a stream for about 300 feet.Lawn is mowed to the raised bank, then the high grass starts up over the mounded bank and down a rocky grass covered slope to the stream. 1/4 of the length is thick thigh high grass 7-10 foot wide. The rest is knee high pasture like with lots of rocks. Bank is roughly a 45* slope. I intended to use a brush cutter on heavier stuff and string trim the rest, then blow the cuttings down over the bank to make it look cleaner. I told them 150.00, which the wife said was reasonable,and I said I would be back in three days to do it. Tonight she called and said her husband thought the price was too high. I am now thinking that they didn't care how it looked ,they just wanted it knocked down. Of course I wanted it to look nice so they couldn't complain about how it would look with all the tall grass laying down. Am I too high?
