How much would you pay for an E-book?

It's really hard to say without knowing the content in it, I would suggest giving the first few chapters of the book for free, or perhaps the first chapter. Or alternatively.... It's become a common pratice amongst e-publishers to write ebooks (shorter condensed versions) and give those away for free download, this enables consumers to see what type of information they are getting from you, your style, content, value and encourages them to buy the bigger package which would be your "master book" I would find a a few people to test your master copy with, give it to them for free, get their opinion's and if it works for them, get them to write testimonials, this will help to promote and validate your work. One of the first questions consumers will ask is "who are you" and "what gives you authority to write on this subject" basically what have you done and achieved, the best way to get this message across is to write a free ebook chronicling your success with examples, or a website that promotes the ebook, you as an authority, even better do both if you can. I wish you all the best of luck

Sounds really neat. I kind of like the idea of making it into several books. I think people will be more likely to buy it if it doesn't cost so much to get the first one, then when they see it is useful to them, they will want the others. Be sure to let us know when you have this ready.
