I cut grass this summer and made decent money. Charge 20 to 30 bucks a lawn and cut out the professional lawn guys. Since your not making a living, you can do that. If a lawn is larger, obviously charge more than that. I will charge 20 dollars up to about a 1/2 acre. After that, i look at it and write a price on my flyer and leave it. Make sure you do a good job though. The lawns will come. You will get a few by word of mouth. If you do this, you will have more than enough money to by fishing equipment(maybe..... lol).
