I agree - that would be an awesome follow up post to garner more insights into getting the start-up from day 1 to selling it :)

I started off that way as an affiliate, but eventually, when I launched LocalPainterQuotes.com, which a year later became CraftJack, we started selling direct to service providers and built a lot of technology that other companies were/are not providing to their customers. The revenue increase really came over 2 years as we had some revenue before we launched CraftJack, but it was still pretty quick growth and all bootstrapped. That's one of the things you can do in LeadGen easier than other sectors (bootstrapping).

it also has TONS of players in it.. my first job out of college was at a small lead gen company that had about 5 people working there. the key i think that company had was a crazy good( or just persistent) salesman that looped in the big players in the various niches, ADT, Brinks, Wheaton, etc..
