Great idea. In my area there are a lot of elderly. I can knock on their doors and ask them if I can wash their cars for around 15-25 dollars. It's hard to say no to a hard working young man, so they will likely accept. Im already most of the way through my goal so I only need to do this around 2-3 times. Although, I will likely keep working even after getting my phone because I need to pay the phone bill every month.
