Live in a small town (7,500 people) so i'll have to think about what people would like or need the most in my area. However, when i was a teenager i would also cut the grass for extra money. When winter would come i would shovel the snow as well. One other thing is my sister used to live next to a golf course. I would walk along the side of the fence on the property where she lived collecting golf balls. I would then clean them up, walk to the road where the cart path would cross to the other side and sell them to people playing for $5 per dozen.
