Hmmm,
What you may want to cover are the questions asked on the message boards. The which kayak is right for me? How do I install this? and so on. One other thing you may want to think about is using your own cash to finance the book, and not get sucked into the politics that can happen if you have someone bankroll it, then have to pimp them or their brand of products in your book for repayment. Just a thought,
