Like many an entrepreneurial venture, Hollis started her Hollywood event planning business in her basement. As she recalls, all she needed was a computer, a phone line, and an intern, which kept start-up costs down. "Nobody needs the stress of owing the bank a million," she says. Today, the company helps plan events for the likes of Disney, Yahoo, and New Line Cinema.
