Sorry to say but as far as I'm aware you will be in beer wasteland
I'm not aware of anything formal as far as a club and don't know of any BJCP judges in the area either, though you are more than welcome to come down to Savannah to a SBL meeting 1st Wednesday of the month at Moon River. Columbia might even be closer to a Palmetto Brewers meeting.
My few times in town, I really only know of one good bar with a good beer selection - don't recall the name but it's downtown next to Nacho Mama's with about 15 taps and a number of bottles as well. Of course, I've only been up for short stays.
