Character Storyboard Design

Hi there
I am publishing book for teaching Arabic to non speaking.
This book will be mostly made of set of dialogues conversations mostly either 2 males or 2 females talking in a standing position with a suitable background at the back reflecting the topic.
For example there are 10 units
Each unit of language will have a dialogue between 2 or 3 sometimes.
Unit 1 Greeting
2 Asking nationality
3 asking about occupation
etc ..
all lessons are available in dialogue in Arabic in the intermediate on my site
I need mainly cartoon Illustrated characters
