Children's Book Ghost Writer

I am looking for a skilled writer to create a children's book for the age group of 4-8 years old. The main theme of the book is about the environment and should be inspirational. It should be engaging and captivate the attention of young readers. The ideal candidate should have experience in writing children's books, with a talent for storytelling and creating relatable characters. The first part of the three book series have already been published and the second and third book storyboards have already been drafted. Need to finalize the manuscript for the second and third book which should be original and creative, and in line with the main theme of the first book. The final product should be of high quality and meet the expectations of the target audience.
