Audio Translator - Japanese to English

We require a cost of translation of a B2B audio file interview Japanese to English lasting approx 1.5 hrs. You can quote either on 'per audio minute' basis or 'per 1000 words'. Repetition, pauses, unecessary words etc can be cut out and there will be two speakers in the room. There are two different interviews to transcribe. This is remote work and location is not important but, if you live in either Tokyo or Yokohama and wish to also quote to actually conduct the interviews as well (face to face) then please add that task to your quotation. We are pre-appointing the interviews from London. You must be fluent in business Japanese as the interviews are within the chemicals sector and some of the words will be technical. In addition to costs you should advise relevant experience and approx (normal) turnaround times.
