The company offered rooms at its Tripoli villa and transport “by our discreet mixed British and Libyan security team.” Its discretion does not come cheaply. The price for a 10-minute ride from the airport, for which the ordinary cab fare is about $5, is listed at 500 British pounds, or about $800.

“There is a gold rush of sorts taking place right now,” said David Hamod, president and chief executive officer of the National U.S.-Arab Chamber of Commerce. “And the Europeans and Asians are way ahead of us. I’m getting calls daily from members of the business community in Libya. They say, ‘Come back, we don’t want the Americans to lose out.’ ”

Yet there is hesitancy on both sides, and so far the talk greatly exceeds the action. The Transitional National Council, hoping to avoid any echo of the rank corruption of the Qaddafi era, has said no long-term contracts will be signed until an elected government is in place. And with cities still bristling with arms and jobless young men, Libya does not offer anything like a safe business environment — hence the pitches from security providers.

Like France and Britain, the United States may benefit from the Libyan authorities’ appreciation of NATO’s critical air support for the revolution. Whatever the rigor of new rules governing contracts, Western companies hope to have some advantage over, say, China, which was offering to sell arms to Colonel Qaddafi as recently as July.

“Revenge may be too strong a word,” said Phil Dwyer, director of SCN Resources Group, a Virginia contracting company that opened an office in Tripoli two weeks ago to offer “risk management” advice and services to a company he would not name. “But my feeling is those who are in favor” with the transitional council “are going to get the nod from a business point of view.”
