Hi Denise,
Your topic is good and the graphics are sharp except for the top ebook cover, but the copy is a bit short. If you add more benefit rich copy, I htink you'll see an improvement in sales.
If you want some good ideas for writing copy, take a look at Dan Lok's
http://www.quickturnmarketing.com his copy is fantastic.
As far as promoting your product, it's a great niche product that you could cover with post cards and other direct mail pieces. I'd suggest going offline to market this and drive people to your website.
I hope this helps.
Have a great day!
Terry
