There are services out there that will do quality transcription that is completely automated (e.g., Bitplatter's FluidData), and IIRC, they're already doing most of the podcasting world's transcriptions for free right now, including Joe Rogan's.
This seems like the more niche market of those who want last-mile, extra-high-quality transcriptions to sell, for which I think they should be charging more than $10.
Not to mention, FluidDATA has transcribed over 8.2 million podcast episodes from over 230,000 podcast feeds.
FluidDATA doesn't expose the entire transcript. It currently only exposes the ability to search the transcripts of millions of podcasts.
For example, you can find podcasts that talk about SpeechBoard and Craig by searching: "speech board" + "craig canon"
