Just my opinion, but you may have not received any responses because your email (that is now in the Share your Work section) sounds like spam. (Mainly because of the way you are talking up your book when you are the author/one of the authors.) Also, when I hear that someone is editing their own book, I assume that it sucks. Doesn't mean that it does suck, but if it didn't, it'd probably be published by a known publisher. Again, just my opinion.
Another thing, if I'm going to take the time to read someone's book for them, I expect them to listen to ALL my opinions, (including editing ones) not just what they specifically ask for. I belong to a critique group that has been a huge help to me. Sometimes I get off the wall, totally unhelpful advice, but I still thank the reader for their time, and mean it. They didn't have to read the book/chapter, they did to be nice, and I should appreciate it.
Also, most of your emails had common spelling and punctuation errors. This site is FULL of authors, we notice those things. And if your posts contain those simple errors, your book probably does too.
One last thing, which is again not meant to be rude, but your original email sounded kind of pompous. Most of us like nice people, so the nicer you are, the more others will be likely to help you/read your work/give you advice.
All of this is meant as constructive criticism. Not as a flame, or anything along those lines.

PS I can't spell worth a crap, so I realize that I may be a hypocrite by making the spelling comment. Spell check is my best-friend when it comes to writing.
