Book of original tales for children about wildlife

I want to write a short book with one tale for children aged 3-6, and I need an illustrator. The tale is original and I have already tested it with children. The tale is about two little wild boars captured by a fox to feed her cubs, and saved by their granny who reaches an agreement with the fox. It's a breaking the rules-danger-struggle-winwin situation, and the moral is that even if the child cannot understand the adults all the time, they are mostly right. The understate aim is also to give the children some more knowledge about wildlife rules and behaviours. The tale is all during one night, and I would like to let the children to use their imagination, with no too descriptive images, but evocative ones. This is the first of what could become a series about European wildlife. Thank you. Diana
