How I can raise US$ 115 in less than 30 days?

One could argue that in a single weekend gardening. The two of you could go looking for houses to be grass mowing, raking, branches in yards, etc. Then just knock on the door and offer to do it for a low price ($ 20 to rake the patio, $ 30 average per acre to cut, whatever). You just have to find some people who want his help.
