The most comprehensive convention held for Hispanic businesspeople in the area will be hosted by the Ibero-American Chamber of Commerce this week at the Washington Sheraton Hotel.

The Ibero-American Chamber of Commerce, which annually hosts the event, has added a two-day trade exposition, an international leadership convention, and eight business development seminars to this year's agenda, said Linda Mayo, a spokeswoman for the organization.

The convention will be held Thursday and Friday from 9 a.m to 5 p.m. at the hotel, at 2660 Woodley Rd. NW. Nonmember tickets for all events will cost about $70, excluding the ticket for the fund-raising dinner on Friday night, Mayo said. More than 300 Hispanic businesspeople are expected to attend.

"{The event} has been growing each year," said a chamber spokesman. "It used to be just the annual gala with Latin music and dancing, but last year we added more substantive events, such as the assembly discussions."

Two local businessmen will receive the Chamber of Commerce's annual awards. Luther Hodges, president of the National Bank of Washington, will be named "Corporate Man of the Year," an award presented to a non-Hispanic for his contributions to the Hispanic community.

Jose Yglesias, president of the defense contractor Syscon Corp. of the District, will be named "Hispanic Business Man of the Year." Yglesias founded Syscon in 1966. The company has grown to a 35-office operation, employing more than 1,500 people and reporting $150 million in revenue.

The awards will be given at a luncheon on Thursday, where Sen. Paul Simon (D-Ill.) will be the keynote speaker. F. James McDonald, president and chief operating officer of General Motors Corp., will be presented with a special leadership award, Mayo said.

The trade show, Proexpo '87, will include 36 booths representing federal agencies and Hispanic businesses. The business seminars will cover such topics as the Minority 8a Designation Program, the Tax Reform Act, immigration reform and conducting business in Washington. The leadership conference will include participation from regional Hispanic Chambers of Commerce, along with representatives from the chambers in Mexico, Guatemala and Nicaragua, Mayo said.

Most of the events will be conducted in English, but translators will be available, Mayo said.
