Kids' Activity Book Design

I'm looking for a creative individual to design a coloring and activity book for 6-8 year olds. The characters will be original kids' characters created by me.

The book should include:
- Coloring pages of original characters
- Mazes
- Connect the dots
- Find the objects

Ideal skills and experience:
- Experience in creating children's activity books
- Strong illustration skills
- Familiarity with age-appropriate puzzles and activities
- Ability to bring imaginative characters to life
