International auto shipping United Kingdom (UK)

Hi there. I am with Let Us Auto Mate Your World Direct and we are a auto concierge service that caters to high end clients through out the globe and their busy traveling clientele. We are in need of a cargo shipping company that can get a shipment of cars from New York to just outside of London in a matter of seven weeks. We are open to all shipping options, although we have traditionally gone with ocean cargo freight liners for this kind of route. We will be requiring that the cargo shipping company have the proper International status permits already in place given that we do not have a large allowance of time to procure them or wait for the company to get them Additionally, there will need to be insurance in place in case anything should happen adversely to our cars, even though we do not anticipate this happening.
