My hunch, FWIW, is that pros do not typically charge by the slide. They
charge by the project, by the day, or by the hour. A slide can have one
image and a handful of words

or it can have zillions of things

Of course, there's also the consideration of how quickly one co-worker
performs the task versus another because of skill level, etc. Faster
people can and should cost more.
If you must have a "plug number" for a spreadsheet, I would recommend
calling your local temp agencies like Aquent or The Creative Group for
PPT specialist rates. Internet-based freelance jobsites also offer some
clues. Search on "freelance design" + "PowerPoint."
