Hi Steven,
I found your book on amazon and you even already have one review, its seems to me you already started with your marketing. Its not easy, I know, but your first steps are on the right direction.
Im not "an experienced book expert" but I know a thing or two about marketing and this is what I would do:
1. First, talk to you. I want to know you, your book and goals.
2. Read the book, cant sell what I dont know.
3. Devise a strategy. I feel that if you have some budget and no hurries, we could set a very specific campaign on Google Adwords. That is, in case you dont know, paying google to direct people to your website (on amazon). Since you pay per click its a safe strategy.
4. I would also try to have more reviews on amazon, event if they are written by friends or family (as long as they read it, of course).
Anyway, hope I can help you. please send me a message and we will talk.
Lucas
ps. dont look at the amount on my bid, we will set it based on your needs.
