Automated Transcription Program Needed

We are in search of an automated transcription program that can run a large number of queries in parallel. The program must be capable of transcribing millions of minutes per month. The audio files will vary in size, but on average run about three minutes each at approximately 1MB per minute. We fully understand that accuracy depends on audio quality, however we are searching for a program that is comparable in accuracy to the many competitors in the automated transcription industry. We would like to begin by offering an interested freelancer a list of sample audio files to run through their program so we may experience its level of accuracy. If approved, we would be interested in proceeding! We are not interested in paying per minute. We want to fund someone to write this program for us, or sell us the rights to use their pre-existing program.
