Yes I know if I'm the writer, I should, but I am wondering if there are people who do this for a living and who I could contact to discuss selling my idea and book to publishers and agents. I just want to get it right. I am writing a nonfiction.

All Answers To Questions

First: Yes, there are - you can buy software to help you. I know, because I saw it being discussed in an agent's blog. She was having hysterics over just how bad the letters were. Write your own proposal. Second: Is this is a fiction book? If so, forget it. You can't sell anything other than a completed, edited, polished novel. An "idea" is worthless.

The only time you will need to write a book proposal is for nonfiction. If you are writing fiction, you write the book first then try to sell it. For nonfiction, you have to have a platform and an outline and sometimes a marketing plan for the book, which is what the proposal is for.
