The post mentions using Google speech-to-text for transcription which seems to be even cheaper?

I'm not sure where you got the $4/hr price, but indeed kudos to OP for building a business around reselling cloud services for profit.

I'm guessing the $4/hr price estimation is based on an average of the prices ListenNotes actually charges to transcribe a podcast, as shown on ListenNotes.com for various individual episodes.

Yep exactly. I randomly sampled some podcasts and looked at the cost vs how long they were.
