Kids book Illustrator

I am looking for an illustrator to create illustrations for a martial arts children's book targeted towards children aged 3-6. The illustrations should be in a cartoony style. We have designs for some of the characters, but others will need to be created. The book will require 10-20 illustrations or more. The ideal candidate for this job should have experience in creating illustrations for children's books and a portfolio that showcases their ability to create engaging and appealing illustrations for this age group. This project is not only for one book; if we are happy with the collaboration, we have at least 12 more books that will need illustrations.
