this really depends on how much you want to make. what kind of mower are you using where you had to refill the mower twice? If a leaf removal job took me 3 hours to do I would be getting close to 300 dollars to blow them to the curb or in the woods. If I had to haul them away its an extra 100 which is standard for a licensed and insured, tax paying landscape company to charge. do some charge less, probably, do some get away with charging 150-200 probably but I get an extra 100 to haul them away.
