You could also try Clickbank which lists and sells digital products. Basically, you list your ebook and other people can sell it on the net through various techniques such as blogs, websites, Facebook, etc. You’re probably going to want a webstie with a sales page for the book as well.
The most successful people on clickbank have some sort of joint venture going with other publishers however. So, you may want to explore those options first and then launch it on clickbank.
My understanding is that Clickbank is more or less a bank. it can act as a receptacle into which your publishing millions are dumped, once people make the decision to buy same, but it is not “where people would go” to “look for books”. Where people “go to look for books” is obviously Amazon, but even better if there is catchiness to the title that IMMEDIATELY implants the idea that the contents of the book are pain relief.
One of the principles of modern selling is that people buy pain relief. They do not buy the actual thing that moves over the counter. People do not buy electric drills: They buy the freedom to place holes in things.
So the idea of such an ebook (to me, to my way of thinking) is to allow people to come (on their own) to the conclusion that the info contained in the book is the solution to their problem or their curiosity and besides, it’s a lousy $3. so what do you have to lose?
Multiply that * 100K and the author becomes reasonably wealthy.
