Someone who does security work for me on the side (for about 12 years works now) manages a team that does this at a large consulting company.
I can't remember exactly, but he told me what they bill him out for and it sounded like NY senior attorney level rates.
He travels overseas regularly on longer term assignments. I told him he should go out on his own but he's not entrepreneurial. He also said that a few of the "sales guys" at the firm already did that with some of the other security people last year.
