Auto detailing

I just heard from a friend that he is starting an auto detailing business. He comes over to the house and works in your garage. He provides all the supplies and details the car inside and out. He says it takes him 4 to 8 hours depending on the state of the car. He charges a minimum of $175. Although this job sounds like hard work and longer hours it seems like a good way to pick up extra money, a possibly a full time business depending on how much he wants to work. I was going to get my car detailed at an auto service place and they wanted to keep it all day and were charging $199. So my friends work is a better deal for me.
