Got a call from a friend who has a syndicated radio show, and he wants to edit down some of his older shows for archiving and "best of" shows. Now, I work full-time as a VO, but I've been a production nut for many years (yes, I go back to the razor blade and splice tape days). I have never done freelance production, so I have no idea what to quote him. My question: what is a fair rate to do something like this?
