My partner and I have come to the conclusion that charging .0025 per square foot on the average lawn after spring cleanup will be appropriate, for example my lawn is 19107 square feet and we have been doing it for my folks for $45 which breaks down to actually $47. Does this sound about right? How about .02 for a really nasty cleanup (lots of leaves, sticks, general crud) and maybe .01 on something that is basically a first mow and a little stuff leftover. These prices include thatching. We also offer Lesco soil tests for $20 and a free consultation on what they want sprayed.
