Sonix might work for you. It's completely automated and can return a transcript in less time than the length of the recording (eg. 30 minute file will take less than 30 minutes). Because it's completely automated, it is not 100% perfect but can get pretty close with a clear, crisp audio file.
Price = $8 per hour of transcription
Upload a file to Sonix and you will receive an email notifying you that your transcription is finished. The email will include a link to the transcription. The transcript includes timestamps, highlighting, and editing functionality built right into the transcript. You can then share it or export to many formats as you wish.
