You may want to consider using my system as part of the promotion of your book – http://www.talkspot.com
Here’s what I did to promote my book ( http://www.kensbook.com ): I set up a mailing list, and sent out each day roughly a page of text. The mailing list grew with each day to several thousand people. When the book was released, I have a large audience of people already waiting to buy the book.
