Audio transcription

Does any of you do audio transcription

I am looking into getting into this field and may need some pointers as to where to find good clients ( freelancing portals are a race to the bottom so I am avoiding that option if I could )

Just seen this.. I know it's late but been doing transcription for the last ten years. For clients Upwork, Rev, Gotranscript, Speechpad e.t.c there are many. It's a good line of business. I started my company and now I hire transcribers
