Greg - I've downloaded your first six chapters because it sounds like it might be an interesting read. You might do well to poke through the Authors threads to get a feel for how others have approached ebook marketing. It's not yet clear that you are aiming at the ebook market. Although Caffeine Nights Pub. says it does all forms of digital publishing, the only book I see looks like a POD; an attractive one, but not digital. You might also look at
www.closed-circle.net, somewhere there I think cj Cherryh talks about her process, although it may be buried in her blog instead. If you think I'm saying perhaps you should start smaller than Amazon or Kobo, you're right.
Best of Luck - I'm looking forward to your sample.
