Children's Book Illustrations

I have written a children's book that needs illustrations! The children's book is about a woman who has a baby. I would like all of the characters to be ducks - there will be a Mother Duck, a Baby Duck, plus two other minor characters (the 'man' and the Doctor) - all ducks. I have attached the text of the book. The book is intended for babies and toddlers, so the illustrations need to be very soft and babyish. Pastel colours will work well. I will need approximately 11 illustrations for the final book. In your bid, please provide your cost PER ILLUSTRATION, plus a sample of how you will illustrate the ducks. You can provide other illustration samples if you wish, but your bid WILL NOT be accepted unless you have provided a sample of the duck illustration. Feel free to watermark your illustration - I just need to see a sample so I know what you can do. If you have any questions, please ask. Otherwise, I look forward to receiving your bid and your sample illustration!
