I don't. I'm sure the military could tell you.
As I was saying to Ms. Mathyssen, part of the issue with costing for the military is that, because of the preoccupations of Parliament over the years, the costing is utterly and completely comprehensive, taking into account all repairs, all upgrading and all facilities.
Going back to your question, if you're dealing with a private sector helicopter, you don't have all of that. They want to make a bit of money on the use of the helicopter for this time frame, so they'll charge you whatever they are charging you and it will be a lot less than what the military is charging.
