What it costs to book speakers

The fact checking continues on some book manuscripts I'm proofing. One of the things I had to find out was how much it costs to book a middle tier motivational speaker these days. The ms said this character made four and sometimes five figures a speech. It looks like that guess turned out to be right on the money.

I spent more time than I probably should have this morning just scrolling through that list and others on that website, marveling at who charges what for a speech, and also at the sheer variety of speakers being advertised.
