childrens book illustrator

I am searching for a book illustrator for an early children's chapter book. I would like black and white drawings throughout the book, about 10 full illustrations and 5 smaller illustrations, along with a cover (in color). The book is about kids being superheroes in a magical city in their minds, so some imagination would be great, although I'm still looking for somewhat realistic-looking images to help kids visualize what is going on.
