I need an illustrator

I have a short children's picture book for ages 5-10 ish. I need the two main (a young boy 8-10 years old and his pit bull dog) characters developed to begin promoting the book, while it's illustrations and finally printing are being completed. I'm open to creative and different ideas!
I will send the manuscript and photos of the dog the main character is based on when an illustrator is selected.

I should add that if we gel with the first cover illustrations, then I would like to continue the relationship to finish the entire book.
Thank you! Renee
