Richard V. Secord has closed his office, effectively ended his business with Iran-contra money-man Albert A. Hakim and is looking for work, according to sources familiar with his situation.

Secord, 55, a retired Air Force major general who played a principal part in the Iran-contra case, is one of the targets of independent counsel Lawrence E. Walsh's investigation.

Although he has given a few speeches, Secord is "not a hot property" on the lecture circuit, said one source, speaking on condition he remain anonymous. The source later added, "He doesn't have a lot of money."

Secord and Hakim, former business partners at Stanford Technology Trading Group International, handled logistical and operational details of the program to sell U.S.-made weapons to Iran and divert the profits to assist the Nicaraguan contras.

They reported to Lt. Col. Oliver L. North, the National Security Council aide fired by President Reagan last November. Secord gave general instructions to Hakim, who controlled the money.

Secord, in an interview last month at his office in McLean, Va., said he was pursuing new business ventures, but didn't say what they were.

A few weeks later, he shut down the Stanford Technology office, Thomas Green, his attorney, confirmed. The telephone number has been disconnected, and Secord has an unlisted home number.

Hakim, who owns a house in Los Gatos, Calif., could not be reached for comment, and, his attorney, N. Richard Janis, was out of town.

About $8 million from Secord's "enterprise" remains frozen in Swiss bank accounts. Ownership of the money remains in dispute.
