Our site
www.cheatingxxxwife.com revolves around Wendy and we do more than triple the $$$ you are talking about, but our site is certainly not a flash yer boobies type of site. I was exactly like you 4 years ago, got into it because Wendy thought it would be a good idea, and I had no idea what I was doing, but her kinky fetishes make it pretty easy to make money.
I couldn't imagine making any real money with a non sex type of site unless you are already an experienced webmaster and new all the tricks of the trade.
