Hello mate. I could absolutely not write 90 pages for you. What I could do, however, is hmm... I became very interested, in your project, based on the name of your book. I love people who are genuine in their marketing/selling. I'm not sure, 100%, what I could do; but I know that, if I did something, it would give you a great foundation to build off of. Damn this got confused... I have some top sales knowledge, that I could present; for the actual ghostwriter to follow up on. The problem is if he doesn't know how to... hmm - possibly I could write a chapter or something. Confused here :(.
Anyway, let me just present the ideas and maybe this will make a bit more sense... I'm all about talking directly to the reader. My copy is very "friend talking to a friend". Copy can never be anything but your personal salesman. You might think it can be less personal but it really isn't. So, whenever you write anything - to sell - you need to ask yourself, if what your saying is something you would say to another person; and said in the way you would say it. So, if the tone of your text is creepy, it's going to be creepy to read. And who makes deals with creepy people?
Read the pm for a sample of what I could provide.
