Adventure-Themed Children's Book Cover Design

I'm looking for a talented illustrator to create a captivating cover for a children's adventure book aimed at 9-12 year-olds. The book is about 40000 words and is written for all children - it is funny and adventurous - but there is a special feature. The main character is dyslexic and my hope is that children who are dyslexic will relate and be inspired.

I want the cover to spark curiosity and excitement and I will need covers for paperback, ebook and audio book. I will also want versions of these images to use on my Kickstarter campaign and in other marketing.

I am also happy to discuss other illustrations to be used throughout the book - I am not sure whether to use these or not as my age range is on the cusp of whether they are beneficial.

Key Requirements:
- Age-appropriate and engaging artwork
- Adventure theme representation
- High-quality, professional design

Ideal Skills and Experience:
- Experience in children's book illustration
- Strong understanding of the 9-12 age group's preferences
- Creativity in depicting adventure themes
- Proficiency in digital or traditional illustration techniques

Please include a portfolio showcasing relevant work. Looking forward to your bids!
