Children's Book Series (2nd grade)

I am looking for a High-Quality Children's book ghostwriter to write short stories for ages 7-8 years old (2nd graders). I'd like the ghostwriter's experience and research to be in the following: biracial/mixed race boys in the United States, confidence building, fostering inquiry and curiosity and discovering self worth and value in others through their adventures. This book series will focus on values like: belonging, acceptance, non-judgement, diversity, empathy, and kindness. I'd like to book to include cliff hangers which keep the reader engaged and want to go on to read the next book. I like to give space to the writer because I do not want to rush/interfere with the writer's imagination/creativity.

I would like the writer to have the correct punctuation/grammar and be willing to have a long-term business relationship.

I am currently looking to pay $100 per 10k words (2000 words per book).
