Ive been to charleston a few times for golf.  there are some good services there, but few good independents. stay away from any service who posts tons or uses ghetto speak (unless you like that).  A Call Away says "no niggas or fatties".  Its pretty obvious they are out for drama.  Abagails is pretty good, they have been around for a while. Same with a place called "Silk Stockings by Amber" a walk in place.  Good luck and have fun!
