I have Bob's Lawn also and he charges us $40 for our lawn care. Think price depends upon when you've hired him and size and amount of work the yard requires. We've had him for a while and if we've ever had an issue, we've spoken to him. There was one particular crew of his that didn't seem to be as careful as we wanted them to be and another neighbor also had an issue with this crew. They were replaced and all was resolved.
We're fortunate, Bob does the yards on either side of our house and the one behind our next door neighbor and also the yard across the street from us, as well as Mom in law's house that is behind our across the street neighbors. Looks great after the crew leaves, all the yards are manicured at the same time...
