I have to give a guy an estimate for chopping down some hedges. They are about 4-5 feet high, and the guy wants me to chop them down to about a foot. I plan on doing this with a chain saw. There are about 20 of them to do. I told him that I would call him with a price. I'm thinking that it will take about 2 hours. And then I would have a dump charge of 20 dollars for each load. So I was thinking about $100-150 for this job. Does that sound like a good price? Or is this really low? Thanks for the help.
