There are only a handful of slots remaining for this year’s Business Expo, held annually by the Cumming-Forsyth County Chamber of Commerce. Jason Mock, director of the chamber’s Small Business Services Center, on Tuesday said just four booths remained unfilled for the event, which will be held Aug. 8 at the Lanier Technical College Conference Center. “There is space for 63 businesses in total and so far we already have 59 of those filled with about two weeks to go,” he said.
