I've seen a few of them around but would like to learn more. These groups that advertise their minimum or average cost and only cut up to a certain size. Do any of them work? I've seen some good advertising with. Seems like a retail type of idea...you know like a hair cut. Seems interesting but yet i feel it's risky or won't work. Also, it seems like only residential would use the service, but maybe I'm wrong. Also would it be a good campagin for college students? Just a thought...?
