I'm looking for a ghost writer for an early readers book.

Hi, I am looking for a creative writer who can brainstorm ideas with me and write a 2000 word (or under) children's book.
-Most of the plot is outlined, but I am open to different ideas regarding the ending and other specific bits.
-The age for this book is 6-8 years old. It requires short, snappy, simple sentences.
-Chapter book layout with short chapters.
-A previous story from the same series will be provided for you to get an idea of the style.
