Tony Sobel of De Pere, Wisconsin is a liver transplant survivor now working full time with his home based business Greenfield Furniture. He sells just two products: Mattresses in a variety of sizes and bunk bed sets in a variety of configurations. He somehow manages this from home: the fact that there is an adjacent shop space is no doubt an advantage which we city home-based businesses usually don’t have.
I’d post a link to his web site, except he doesn’t seem to sell on the web. He uses classified ads and that good old ‘word of mouth’ to reach his customer base. I take inspiration from people like this.
