Illustrator and graphic designer

I am looking foursome to
1. Draw some cartoon illustrations in my book
2) Design book cover.

I have a three part mini series I am writing for adolescent/teenagers. It is called Me, Myself and I. The three part series is Friendship and Relationships, Self Esteem, Identity and Emotions and the third one is My Body!
Each book is around 10,000 words. I would need someone tread each manuscript and decide what illustrations would be suitable. I am looking for cartoon simple drawings in line with the written material. I would like the books to engaging for the reader and have similar theme across all three of them.
We can start with one book first so please offer your proposal based on one book!
