Illustrator Needed for Children's Book Series

I’m looking for a professional illustrator and graphic designer for a children’s book project. I already have some character designs (only as images, not source files), which will need to be adapted into the book.

The first book will be 20–25 pages long and is part of a larger series of 15 books in this edition, with 5 more editions planned afterward. I need someone who can work efficiently and help complete all editions within the next 2–3 months.

Key requirements:
Strong experience in children’s illustration and graphic design
Ability to work quickly while maintaining high-quality output
Must provide real-time progress updates
Comfortable working in US standard time zone for coordination
Final delivery must include all source files of this project and each design
Full ownership and usage rights of all illustrations will be transferred upon project completion
Looking for someone who can work diligently, reliably, and long-term at fair rates, as this will be an ongoing project

If you’re creative, reliable, and able to commit to this timeline, I’d love to collaborate with you.
