Lloyd and followers, here is some advice from a professional writer: asking people to pay you to include their stories in your book screams amateur. The way it works in the real world is the author pays other people to include their stories in a his work of non-fiction. It is payment for the copyright to include their story.
I don't think your scamming people, I do think you're taking advantage of people that don't know any better. You should take some classes on the profession of writing, you might learn how to do it right.
