Adam,
AudioAdvice has a home theater installation part of the business, as well as in-house audio technician. Might be something there for intern.
I know someone who worked at Cary, you'll meet him if you come to our next listening party. Something in the next 5-6 weeks. Growth wise, they are past prime, imo, but might be a good learning experience for intern.
Temp agencies are sometimes a good place to get a foot into a technology position. Your college should have job advisors for non audio internships, I'm sure you already know about that. There is a lot of tech work in the Triangle and "down east." Aerotech is one of the biggest contract joints in town, for after you graduate, but a real job is usually more fun than a contract.
