I have to honestly say I would not pay money for any of those topics as I have found so much information is available free either on-line or at the library in published book format. Being an entrepreneur myself, I have to carefully consider every purchase.
What I see online is a number of people offering free advice first, and if you like it and want more, then you can pay them for the e-book. I am not sure if that is working for them, and maybe that is what you already have planned. Two such places where I have received free advice that was good and where they also offer e-books are: vivavisibility.com
. Hope those links are of some help to you.
You probably know vastly more than I do about the e-book marketplace, so just take this as one person`s opinion.
The reason I popped in on this post is that I am a product developer, so I am interested in new products. I don`t generally think of knowledge as a product though, I think of knowledge as a result of the learning process. That would make a knowledge giver a teacher and not a salesperson with a product.
You probably are a wonderful teacher since you have so many good book ideas. Maybe people would pay to take a live class with you. I think the human touch is overlooked, and people would pay to interact with a great teacher in person. A friend of mine worked for a corporate training company for a while, travelling and teaching on topics similar to yours and selling the company literature and tapes. That was a great experience for her because she was getting paid to see what it is like to become the sought after expert in a field and what it takes to sell knowledge.
Hope there is something of value in here for you.
