My little part time repair business I can't advertise so it is 100% word of mouth. The government will want their cut otherwise. cash only, no repair bills, buy my parts retail. Down the road from me another person tryed to run a small repair business the same way but he put some mowers out in his front yard for sale and a sign for repairs. He soon found out that he was being watched and had to close by order of the town. They say this is a free country but don't let some older retired person try to get a little extra spending money by running a small business that isn't hurting anybody.
