Nanci,
I have used stock sites to get the lay of the land, but remember you have created a custom image for their use. They can't actually get what they need on a stock site. Do not use the royalty-free comparison for pricing, this sites use volume sale on many thousands of uses of an image to make a profit. You should use rights-managed images for an understanding of a more realistic custom image pricing structure.
https://www.gettyimages.com may be a better comparison site.
Here is a list of 12 sites to consider looking at: https://www.creativebloq.com/graphic-design/find-stock-art-1131687
Again Royalty-free images should not be part of your equation, unless you plan to sell the image to thousands of users and have the where-with-all to do that sort of thing. You are doing rights-managed custom art for a client and should be making a living wage for the time you spent on it (in theory).

Thank you so much, Britt. I will look into the unlimited use license amongst other things noted. In the meeting today it looks like they want to use one of my variations of one of the illustrations for tee shirts/ hats/ stickers/ stamps which has its own questions. Though they don’t get much from sales of these things, as a small not for profit the illustration in question becomes kind of a logo.
