Check your public library for this book: 2008 Children's Writer's & Illustrator's Market. I haven't looked at it, but I have used the Writer's Market books in the past. They contain information on payment rates, contracts, publication rights, etc. Writer's Market used to contain guidelines for illustrators for some books and serials. You may want to glance at a recent copy of that, as well. Can't hurt to look. Might be a good starting place for you.
Good luck.
