That's why I asked. Obviously I had no idea what I was asking for in particular the thought of using a professional hadn't even occurred to me. After sleeping on it the idea becomes more and more appealing as then I don't have to be responsible for our entire groups failure because I hit the "Bennett hill" button half way through.But when someone says "help me spend not nearly enough on gear I don't understand to do a task I'd rather not do" the answer will always be "find someone who WANTS to do it and pay them what they ask for."
Good on ya. Everybody on set can look at an image and say "that's too dark/light/blurry/close/far/vivid/dull/etc." Everybody on set can listen and say "that doesn't sound good." Knowing what's wrongis most of fixing it and it takes more experience to identify sound problems.
