You can do as I did as a young lad, get the lawnmower a tank of gas and jump on the bike.....go around to houses that need mowing and you will surprised how many takers you get......alot of them will have you do it all summer. My kid brother followed in my shoes after I got older and he was knocing down 200.00 to 300.00 a week and we are talking back in the early 80's
