Children's Book Illustrations

My 6 year old son has written a book called 'Buttface Boy' and he wants some illustrations to go with it. We would like to print out the book with the words and illustrations. We would like you either to just draw the illustrations, or to lay out the book. We were thinking of printing it as a photo book, unless you can advise otherwise. If you are interested in this project, we can give you more information about what each character looks like.
