Transcription of 650 minutes in 4 days

We have 12 files, they are in clear and audible English language. Each file is an interview with someone. The total length for all interviews is about 650minutes. We want to transcribe them into 12 files, with highest quality. This is a rush job so preference is given to those who can complete it in days. We know there are automatic methods online, you can use them, however, they are not accurate. If you plan to use them, you still need to go over the entire audio files and check the work word by word.

Each interview will be one person (called the interviewer) asking questions. And another person (different names), answers questions. Your transcription will identify these two people and transcribe for each.
