I need a short children's story writer

I have an idea for a children's book. I have got the name, the main character and the purpose of the book which is to help children understand the importance of values and how to live your life aligned to values. It would be a short story with humour throughout.

It's a personal project, I'm by no means a copywriter or a storyteller so need help fleshing out the story to make it into a fun & enjoyable children's book.
