Children's books in different languages

I am looking for a writer who can create children's books in Spanish for an audience of 8-12 year olds. The ideal candidate should have experience writing in this genre and be fluent in Spanish. Each book should be more than 40 pages long and have engaging characters and storylines that will captivate young readers. The writer should be able to produce high-quality work that is both educational and entertaining. If you have a passion for writing and a love for children's books, I would love to hear from you.
