I will keep your offer in mind, but I'm currently leaning on one of our very busy other members (Sadako) to finish this job, and I'd prefer if the same translator did all three films. The reason is that the Japanese subtitles need a little more than just transcription, they also need re-translation in places (for example, SRT files can't really deal with Furigana at all), so there's some stylistic choices and I'd like consistency between the films wherever possible.

I'm hoping to have text versions of the Japanese ROTJ subs in time for the next release of the ROTJ Despecialized Edition.
