I havnt written it yet but how does one get it published? I am doing my own illustrations. how do i format the pictures? any advice on the size of my pictures? Thanks!

I have been thinking about writing a childrens book. Does anyone know if there is a site where you can post a story and people can tell you if it's good enough to get published?

My Book is going to be 20,000 words, and should be available worldwide. Does anyone know how much books I could sell?

My mother and I have found a publishing company that is interested in publishing a book that we wrote. We have received a copy write on it. Are we in essence selling the copy write to the publisher? And if the title and sections of the piece are altered, does someone need to re-apply for a second copy write? We are obviously novices but thrilled that our book will be put in print! Thanks
