I'm sure you could get by with a moped, even if you're further away from school. In SC if you get your license revoked you can't drive a car or motorcycle but you can still drive a Moped. Its not uncommon to see somebody on a moped on some major highways, Not Interstates. It wouldn't be totally unheard of for you to drive 15 miles or more on a moped. I'm sure its not incredibly safe, but it can be done.
If you google CCU and Roommate you'll find alot of sites with stories about a CCU roommate shooting... If you root though all of that mess you can find a few sites like this one that show posts by folks looking for room mates:
Roommates around Florence, SC - Oodle.com
Some of the ones on that site are from all over the state but I saw at least a couple in Conway.
