Speech to text transcription of 50 hours of voice-recorded discussions.

I have recorded about 50 hours of discussions on topics of business, economics and finance. I am seeking for the speech to be transliterated, or typed word for word, into text. I will check and mark the intermediate work in process. If words have been missed or typed incorrectly, I will highlight and mark that point. Once the text file has been re-edited for highlighted omissions, the project will have become completed to specification. You must have audio management software to moderate the pace of the speech and match your transcription speed.
