Cartoonish Action Illustrations

I'm seeking a talented illustrator to create cartoonish vector illustrations for a book. The illustrations should depict characters in action and are targeted towards an adult audience. Will require approx. 30 simple illustrations using my own pre-designed characters, e.g. depicting confusion at a maths sum or a visual addition to a written word definition. The characters already exist and the situaltional illustrations will be my copyright once full payment is made.

Key requirements:
- Cartoonish (stick man) style
- Scenes should feature characters in action

Ideal skills and experience:
- Proficiency in vector illustration software (e.g., Adobe Illustrator)
- Strong understanding of character design and dynamic poses
- Experience creating engaging illustrations for adult audiences

Please provide a portfolio showcasing relevant work.
