Flat vector illustration

Hello. I am looking for an illustrator for my son's first book. It's meant to be both an E-book and published into a hard copy. I would like the main character in the book to come alive with rich illustrations and graphic designs for the quotes in the book. Please skim through the first pages of the book and let me know if this is something you can do. Please look at a sample of what I am looking for but the illustrations should look better than this. The book has 10 chapters. I would like at least 2 scenes per chapter. Anything appealing to teens would be great. The main character will be in every chapter. I have included the sample of the illustration style I want for the main character. What is missing is just to make sure the illustrations goes with the story to bring each chapter to life This is what I am hoping for. Chapter 1. Illustration: A lonely boy, watching from behind the classroom window, his friends who are playing cheerfully in the schoolyard. Chapter 1, 2nd illustration: A boy who was looking in the mirror in his room. Observe himself. Seeing who he was and what he wanted to be? Chapter 2, 1st illustration: A boy is reading alone on a park bench, he is enjoying his own time with a happy face. (In this illustration, also insert a picture of the transformation of the caterpillar into a beautiful butterfly) As for the pages with the quotes. He wants 3 quotes per page and any graphics and funky fonts that clealy bring the quotes to life. Looking forward to hearing from you. Thank you
