I have experience working as a freelance transcriptionist for rev.com. So far, I have completed close to 20 audio transcription jobs for them ranging from 20 minutes to 2 hours. Of those jobs, I have been rated by customers on 3, and have received a score of 5.0 / 5.0 on all jobs. 0.50 cents per audio minute for clear audio files with 2 or less people. Rate increases for files with additional people, or lower quality audio files.
