<shameless plug> I actually just announced the launch date for my self-published ebook this morning: http://www.petekeen.net/announcing-mastering-modern-payments... </plug>

I've been working on it for a few months after reading Nathan Barry's excellent book Authority. Based on that I started a mailing list right away and have collected a few hundred email addresses that I can market to.

I can't say I have any concrete advice (bdunn's advice sounds great, though). Best of luck to you!
