Looking for a Japanese translator

We have three interviews in Japanese that we would like to have transcribed and translated into English.

They are professionally-recorded interviews about World War 2 experiences. There may be some terms to verify--place names generally. We can help with any Internet research. Speakers should be identified. The files will be auto-transcribed in Japanese, so we want those automatic transcriptions to be edited and then translated into English.

One of the interviews is 112 minutes long, the other one is 130 minutes long, and the last one is 62 minutes long, so that's a total of 304 minutes (5 hours).
