I need artist to illustrate memoir

I am looking for simple drawings of people, specifically grade school children, college students and parents, mostly caucasian, but also a few ethnicities. Drawings may include college background (very simple), and around the home items. I can supply the drawing I need for the cartoonist to draw it more professionally. The drawings I am looking for are range from New Yorker Style to Diary of a Wimpy Kid in nature.I can be PM'd for specifics. The project will be a published book, or series of books. I am looking for a specific style that fits my budget.
