We are hoping to get a new helicopter within the next 3-5 months that will allow us to carry higher end HDV cams or Cine cameras.
I've never quoted an international shoot but I'd guess somewhere in the area of $3,000/day. plus travel costs. We're significantly cheaper here in the US.
Are any special permits required to fly a UAV (unmanned aerial vehicle) in the proximity of an airport as you stated? Here in the US if you fly within 3 miles of a controlled airport you are requested to get clearance from the FAA.
