I have a 2-volume e-book available that is the most comprehensive you will ever come across. I'm selling these as an e-book because publishing houses would want to sell hard copies for over $75 and paperbacks for over $50. The e-book is available for $39.95, payable by Postal Money Order.
Volumes 1 & 2 total over 950 pages! This has been a 4 year project and is not a simple, quickly put-together publication. It is everything you need to learn from, get started with, and use as a reference from here on out. Novices to Adepts will find all the information in one location!
I'm still working on Volume 3 and believe me its as comprehensive as (if not more so than) all the others! That volume alone will be close to (if not over) 200 pages by itself.
I set up a tab above for "Services for Sale", click on that to access the discussion for the book sales. In the discussion is the entire Table of Contents for the books.
