To answer your questions:

- Yes, the domain area was something that I was interested in already, but not necessarily practised. - Quite honest, I chose it purely on price and the design of the items bought. The dev put in effort to get everything designed nicely. - No, not at the time. It was a rails project so quality was not considered since its too easy to add on/rewrite where needed - Got customer lists, source code + design source, social media pages, analytics, payment profiles, domain. - I had a network locally that I knew I could sell to. I sold hard and 3 big agencies are now using it at a decent monthly fee. - Definitely! I'm scouring 1k daily now and have found a few other gems.
