childrens book

I am looking for a professional to create a children's book for ages 4-10 years with a length of less than 10 pages, based on the educational/learning theme. This book should communicate an important lesson to the reader, be appropriate to the selected age group, and be engaging and exciting. As I am an Occupational Therapist, I am wanting to create a book which targets a topic close to my heart. Ultimately, I am looking for someone with creativity and expertise in creating a unique, educational children's book.
