I've heard of Jim Morgan and his simple and effective strategy to make money using his basic woodworking skills. I know a retired couple here in town who spend many weekends, traveling to various venues where they can sell the products they make during the Winter months. They travel, and they make a nice supplemental income.
Jim started his woodworking business with NO capital, a few shop tools, and a lot of nerve, in a small 10x20 foot space and grew it into a 1,400 space in the first few months while still remaining as a one-person business!
