1. Do research to see what is selling on Amazon. 2. Find a reliable dropshipper. 3. Get their merchant account. 4. List your product creating a long tail description and good article on product's page. 5. Backlink the crap out of your Amazon page using e.g. fiverr gigs. 6. Once you rank, you will start making sales. Amazon like Youtube has a very high DA - 99. Amazon pages will rank very often without any backlinks, I'm sure you have seen it a lot of times if you ever ran any sales oriented searches. Firing some backlinks will only boost your product page even more. Oftentimes even if you have a higher price than your competitors, you will make sales anyway since you are ranking on Google. If you are wondering how to optimize your title have a look at my other thread here. Hope that helps some people who are interested in a quick business scheme.
More and more authors are refusing to use Amazon. Saw this the other day too. http://www.csmonitor.com/Books/2014/0711/Children-s-book-author-refuses-award-backed-by-Amazon
