Audio transcription

I would like to get transcriptions for approximately 2 hours of digitally recorded interviews. I have two recorded interviews in .wav format. The quality of the recordings is generally good. The quality of the written files is not overlly important. I can accept spelling mistakes, paraphrasing where this makes typing easier and ??? where words are unclear, provided the sense of the sentences is clear. I would propose to ftp the files for transcrption so the provider would need to be able to receive these. I need a turnaround in the next week.
