I had a regular client who always wanted to film, so I told him he had to edit the film so that neither of us could be recognized and that I would then be posted on Adultwork. The first time he took about a week before sending me the edited copy, just the original, but about a week later he sent though the edited version.
He did this three times, and then told me it was taking him about 20 hours per video to do all the editing, I didn't help by telling him to make more changes. After three he decided it wasn't worth the effort, but I made about £120 on selling the shorts on Adultwork.
Might be a solution if you trust the client.
