Writing high quality Free white hat SEO book

(I planned to post it in Making Money section but didn't got perfect sub forum so posted here, please change the forum if I choosed wrong category)

Hi guys,
I am writing an SEO book which is planned to be shared at free of cost. I am trying my best to make it a high quality ebook that can be understood and implemented easily by newbie to middle level SEO professional. Here are some of my plans, I would like to share with you and get some more idea in this project.

The ebook will contain:
* On-Site Optimization tutorial
* high Quality Illustrations for better understanding
* Printable Friendly so that user can use it as hard copy
* Newbie Readability Level
* Copywrited Article for high quality

Revised Versions will contain:
* Off-Site Optimization (1st Revision)
* Google Webmaster (2nd Revision)
* Google Analytics (3rd Revision)
* Google Adwords (Not Sure)

I am planning to submit the ebook to mass community and expecting some real serious number of downloads.

The work is almost half completed and dated to premiere within 2 months. Do you guys have any suggestion or any monetizing method for this?

I have some monetizing method but it would be great if I can have option to choose from.

Thanks

Give the book away, build a list and promote other seo related stuff to them...
