i was just wondering what most people are charging for aerating a lawn and dethatching a lawn. are you charging by the square footage or by the hour? I am planning on using my walker mower for the big areas with the thatching attachment and the power thatcher for the small areas. any good feedback will be very helpful. i am in my second year of actually doing this as a side business and just want to be charging what is fair both for the customer and for myself not to be doing it for free.
