As I said to daltong above, let me think a bit more. We're talking at least a month's full time work here. Well, just a guess. A bit under seventy hours of audio, and I can't imagine being able to transcribe in under double the runtime. I'd love to do this "cheapo" but also don't want to take advantage of anybody, or leave anyone feeling stuck and grumpy about a bargain turned grim.

(Plus of course there's one other person on the tape whose permission I'd have to secure if anyone but me does the transcribing.)
