Hi,I'm 8 yrs old, raising money to publish a book

Hi, my name is Adetola I am 8 yrs old. I just completed 3rd grade and will be in 4th grade by September 2020. My interest in writing started when my mother told me that to be a great Attorney, I must be a great story-teller. That aroused my interest in writing.
In 3rd grade, my beloved teacher taught me about "The narrative diamond" and I actually wrote my first book as a class assignment. I just completed writing a bedtime storybook of over 750 words for kid ages 3-5. I need money to publish the book. I didn't know it cost a lot to publish a book. 
I plan to donate 50% of the proceeds to any charity of choice that supports children literacy/education in Africa. This project is not a money making venture for me instead, I will be the most proud 8yr old to walk into Barns and Nobles and see my book on the shelve. Also, I want to inspire other little kids that they can do anything they put their mind to do.
I plan to continue writing as long as God gives me the grace, while pursuing my dream of becoming a great Attorney. I sincerely appreciate your donations and kind heartedness.
