audio transcription of 10 hours of audio

I had a consultant come to my office and recorded it. I need someone to transcribe it. There are 10 hours of audio but lot of meaningless conversation/interruptions though out. You can leave out the meaningless conversation/interruptions. There were typically 2 people and sometimes 3 people on the recordings so I need their conversations separated. EX: Person 1: ~~~~~~~ Person 2: ~~~~~~~ This shouldnt take too long for a good transcriptionist
