Should I hire book cover illustrator for my book?

Many successful entrepreneurs who come from different backgrounds. They want to share their successful journey with the upcoming generation to be an entrepreneur. I have written 2 chapters of the book, but due to lack of time it taking too long to complete it and make illustrations. I was told about book cover illustrators for hire in New York can put your verbal story into words and can make illustrations as you want. I really want to hire one. Can you guide me on it?
