Hi there....I appreciate your advice. I have a lady with a two acre lawn here in RI. The largest job I have done is a little over an acre and I have charged $100 fo that job. What do you think for a two acre lawn...flat with few obstacles. I have a 48" Scag Walk Behind mower as well as a commercial lawn boy and a toro Recylcer self propelled...both are 20". Thanks for the help. ps. I have two sons and another young man who helps me.
