"Magic of Savings: An Introduction to Economics for Children"

I am a student from Kazakhstan and I want to self-publish a book on Amazon. It is a story of girl Elle and her piggy bank Goldie in the adventurous magic journey learning advanced Economics in easy language suitable for audience of children from 8-12 ages! It will be a non-profit book where I would direct all the profit from the book to children in Africa for their educational opportunities. I am looking forward to your response! Here are my ideas and drafts but I need professionals.
