Expedited Package shipping to United Kingdom (UK)

I hope there is at least one company who reads this post that will send me some information on expedited package shipping to United Kingdom (UK). I will ship this package from Phoenix, Arizona, so I am fairly near to a major airport. The package only weighs about 6 pounds, and is fairly small at about 2 ft by 1 ft by 1 ft. The contents of this package are fragile, so I also need information on how I can properly prepare my package for shipment. Does your company supply packing materials? Do I need to purchase them from another source? How much is adding insurance coverage to my package going to add to the overall cost? For that matter, about how much will it cost to send this package to the UK? The package is going to London, so it will stay on the main routes. I am looking to ship this package right away, so if you can reply to my inquiry fairly quick, it would be great. Thank you so much for responding to my questions. I look forward to reading your information.
