Sounds like you've got the right idea, and I agree with not dismissing anyone, you just never know whose gonna shine.

Since you are writing a book for this crowd you could develop a "system" for these people. Something like a no money down system that teaches them how to make money with no money (bum marketing) then teaches them how to reinvest that money to start building a business (hosting, aweber, etc).

That would be a great resource for someone in the situation you've described. Not only that, but once they do start making money, you will have built that trust with them and you can then start to market other products to them.
