Book about raising a horribly troubled boy that made it.....

I am looking for someone to ghost write a book for me. It is to be about my son that was extremely difficult, starting with getting kicked out of three preschools and me dropping him off at a drug read facility that he then runs away from and gets picked up on freeway trying to walk home (miles away from home) He was told by everyone he'd become nothing, including myself at times. Had an alcoholic, drug addict/dealer biological father that had nothing to do with him. After all his troubles-which I mean troubles, he proved everyone wrong and became a United States Marine. This book will be sad, hilarious, and I think a comforting book to mothers out there raising bits that they believe are going no where. Everyone that knows us tells me to write a book on it. I am a high school teacher and do not have time. I truly believe this book will make it big. My budget is small but am willing to work a percentage out in case book does well. My father is an attorney and would write a contract up stating so. I would like a writer that has humor, because my child was difficult yet we laugh many of the things now, like getting a call while he was in Africa with a group and they were going to send him home for drinking at a bar....age 16 at time.
