Illustrator for Children's Books

I'm looking for an experienced illustrator to create images for a children's book. The illustrations should have a realistic style with a lot of details. The book is aimed at 2-7-year-olds. There will be 24 pages, 8.5" square, full body cute characters, full-color pages with bleed, and be happy and fun in an imaginative way. The story is about an old cowboy, a young girl, a pony, and a mom. Details are important in regard to the horse tack, and pony. If you think you have what it takes to create beautiful illustrations that capture the attention of young audiences, please submit a proposal.
