Writing.Com General Discussion

Hey everybody and anybody; I am a nurse by trade but haven't worked in a while. However, a friend of mine has a mother who is in senior living and needs some extra help, so I am helping her. She is a delightful 84 year old Italian woman who is amazing. I told her I was interested in writing a book about her life and she is so excited about the idea. Apparently she has been wanting to do just that. Legally where do we start, drawing up a contract? Do you know any publishing companies that would be particularly interested? Thanks for any information you can provide. Any places that can give me an idea about how to organize a biographical novel would be really good to know.
