Edit: I think this request was very ill-formed of me, and I apologize. I do not want to undervalue people's time, and the cost is so much more than I realized it would be. I appreciate the responses. Given that this book might end up for a very small audience, it was very unrealistic to ask for anyone to illustrate it. I do thank everyone for their time.

I saw a similar post earlier, but I did not want to have to pm every person who responded.
I assume you could get a sample of the art? I assume there is a way to know they are not using AI. I could assume more, but I just don't want to keep assuming.
How do you "vet" someone as an illustrator? How much should you expect to pay? Would an illustrator feel good getting "royalties" or whatever if it sold, or would they just prefer the flat rate?
I realize that most books don't make it big. I am artistic but don't think I could make the illustrations that would make the book exceed some sort of amateurish attempt at a book.
Edit:
To clarify, I am happy with illustrations that look like colored pencil drawings if they fit the theme. I've got three children. I've read them a lot of books. I'm not looking for a complicated and intense illustration.
I'm reluctant to pay much of an upfront rate for one sample pic. I get that time is valuable, but I've already gotten at least 10 pm's from illustrators, and it would get pretty pricy to pay everyone that upfront fee, only to find that the sample is nothing like what I had in mind. I have about 30 illustrations I would want in the end. While I am reluctant to pay a lot upfront, I would be happy to discuss the final cost for those 30 illustrations. I get that many would not want to even create the first sample, given a very little initial financial return on one drawing, and I respect that...
But if anyone is up for it, here's what I would want to see as an example:
Sammy is a sloth. He is of the age where he still needs help a lot of the time, but he really wants to prove he can do things on his own.
Illustration: Sammy sits on the floor, struggling to tie an enormous shoe. His tongue sticks out in fierce concentration. Mama watches in the background with a patient smile.
