The two things I know about South Carolina is 1. There are lots of BBQ places and 2. There are lots of golf courses. I would think you could bring those two things together. Try contacting some of the local golf courses to see if they may have a need for your services. Some courses only have a small deli that may serve a cold sandwich and hot dogs. Maybe they can resell your BBQ sandwiches? Just a thought.
