Children’s book illustrations

Looking for someone to illustrate a children’s book.
Having the text currently edited.
Looking for an experienced illustrator who can design in a classic/ timeless style.
Please ONLY respond if you are able to draw like this. I have already tried freelancers who could not create this style.
I am looking for illustrations where the children look similar to the way this illustrator works: https://www.instagram.com/mandysutcliffeart/
