Just for reference. I am an in the south central of the country, in a smaller market and my location sound rates are $700/10 portal to portal plus $195 for a basic rental package. Mileage rates apply. For the agencies that don't have the budget, I do offer half-day labor rates, but I keep the rental package at the same day rate. My basic package is a boom mic, 2 lavs and a mixer/recorder. I throw in some extras like a slate and sound blankets for added value, but that is about it. Anything else requested is an a la carte day rental. For larger markets that aren't very saturated, I would definitely think about raising your rates.
