Worth noting (as anyone who has done transcription knows) that $1 per audio minute is very different from $1 per minute paid. For all but the most talented transcribers (the ones with special pedals to start/stop the audio), it takes 4-6x times the length of the audio to transcribe. $1 per audio minute, you'd be realistically making more like $10-15 per hour for 50 minutes of audio.
