I co-own a media production company in a small southern town actually (East TN) and for four hours plus editing charge, I would probably charge anywhere from 800 - 1100 but, I own my equipment so add whatever your amount is on top (or subtract about 100 or so and then add your amount to it). And honestly, we are the cheapest outfit in town, our only competitors are not very good and charge exhorbant rates. So, if you are the only option, sometimes you can charge a good deal more for it.
