I need English to English Interview Transcription: 6-hour audio available

*Purpose:
Postgraduate student conducting research interviews recently.

*Time frame:
I will have 12 files available from now to 12 November, averaging 18 - 30 minutes per file. That is less than 6-hour audio files totally. Currently I have 4 files to give you now, and will conduct 8 interviews by 12 November.
The deadline of all of your transcription will be by 17 November.

*All the 1-on-1 interviews are recorded either in cafe using iPhone, or online using Skype, so the audio quality is not bad, and no difficult accents (most British English)
You only need to be aware of what you hear in English, and ensure that it is within the context of what is being discussed in English.

*The academics budget is limited, so the proposed budget of 12 files is total £50- 60.
The transcription won't be published, so this job is NOT required experienced level of professional editing.

I greatly look forward to your applications.
