I have a specialized method of transcribing video and audio files mainly English Language that involves two people working on the same file at the same time. IIf the audio is clear then for a one hour file, I can deliver this work in one day with absolute quality word for word or corrected to remove improper English as you may wish. I would also ask you in case the file have slang sentences if you want them corrected for proper English or you need it word for word.
