First of all, you have broken the forum rules by double-posting your thread. The content is slightly different, but it the same exact thing you are pushing.
See here :
https://bitcointalk.org/index.php?topic=3906330.0 . Then you say that there are already too many people using this method, when someone asked you about saturation. Now you're mentioning that you only need a few more "partners" and this gives me pause, because how would the people purchasing your e-book be in any way your partner? The sales pitch here is very unclear and very unattractive, simultaneously.
