Help me publish

advise needed to publish

I have the opportunity to publish with Fulton publishing. The book is listed in my material here on writing.com. The book is Generation Witch. I have been homeless for four years living in a hotel, and now barely making it on a preschool teacher's salary. I am working on my Master's in Early Education in Leadership. This credential will help with getting a raise. I would appreciate any help getting the book out. I once had a book published "Emotions from my Heart", but I did not have money to merchandize it.

Thank you for any help or advice.
