Cartoonish Everyday Life Picture Cards

I'm looking for an illustrator who can create 50 different, cartoonish-style picture cards depicting separate cartoon type characters (e.g. a truck with a face, a balloon with a face) for preschool to school age children (ages 4-8) to help with Speech Therapy practice (i.e. a different picture to represent each speech sound).

Ideal Skills:
- Cartoonish illustration skills
- Understanding of primary school themes and humor
- Experience in creating children's educational materials
- Ability to draw specific (but simple) mouth shapes to match the different sounds.

Please provide a portfolio of similar work.

Please use a bright and vibrant color palette for the illustrations.
