Thanks. I have spent a lot of time thinking about it and I feel pretty confident that I know the niche I need to pursue and that it can and does make money for some people. Still, well-meaning folks sometimes try to discourage me and tell me "it's not a real business" and stuff like that. Actual figures are helpful. I do still have a day job, so I don't have to be some overnight success or something.

Take care. And best of luck with your endeavors.
