ANOTHER PLACE TO FIND (MOSTLY) SAAS ORPHANS
I ran across this website where a lot of SaaS companies are up for sale. We used to call these things "aqua-hires" because at BigSoftwareCo I worked at, we buy em and the purchase was peanuts considering the talent and some code bits that could be features in our main products.
I have nothing to do with this site. It just is a fascinating site which may catalyst some ideas for you or, who knows, you pick-up a little software company grab some interns to help code it and off you go.
