Take a look, if you please, how Librivox crowdsources audiobooks with a volunteer force of readers. Maybe this is a way forward for Permies.

Librivox audiobooks are in the public domain. And they are free.
Permies audiobooks would be copyrighted. And they would be for sale.
However, having an all volunteer permies force recording chapters for free (or perhaps for free access to the finished product) would foster world domination, because...
With very little overhead, the audiobooks could be sold for chump change and still bank some coin.
I, for example, would be willing to record a chapter. In a quiet room. With a good microphone. Pronouncing words correctly (that is a thing in audiobook land).
I wouldn't be willing to record a whole freakin' book. But one chapter? Absolutely. I bet I'm not the only one.
