Transcription of interviews

I have 3-4 recordings of telephone interviews of between 20 minutes to an hour between 2 people that needs transcribing. The audio quality is mixed as some calls had disruptions, in which case the transcriber can put in a time stamp.

Ideally you would use a transcription software such as transcribe.wreally.com

Ideally you should have done transcription before.

I'm looking to get someone to take on all interviews at a rate per 30 mins of audio. Please indicate the rate for this in the quote. I need these done by Saturday morning, 17 December.
