Italian to English Translation

We are looking for a translator to work on audio files that were taped in Italy on a shoot for a project about the Pope. We need the audio translated into English. We have quite a few tapes that need to be translated but more specific information will come later. Quality of translation is very important and we would like to know about your experience, training, and references. This is for a nonprofit organization. Please send information (above) as well as what your customary rate would be for translating Italian to English. Thanks very much!
