Have you considered placing tiny classified ads in thousands of newspapers?
Seriously, I think maybe you should consider more of what Sly is saying. If flipping is your thing and it's what you know maybe make an ebook on the ins and outs of flipping and how to make a living at it. Lots of people are always looking for ways to be self employed and if it wasn't a big investment for them and if marketed right you could do well with it.
