Hey Bill -
I have had boats there for the last 8 years at 4 different marinas. I would absolutely recommend Isle of Hope marina on the ICW. call Patty, and you are welcome to use me as a reference if you would like. They stay very full so you would need to call in advance. a monthly rate at any of these may be less than 2 weeks at the daily rate. Isle of Hope is charming and was not burned down by Sherman in the Civil War. Lovely homes on bluff drive located on high ground that the American Indians used to call home are all around the marina. Very Clean facilities and store to keep Admirals happy. Secured and safe. It is a 4.5 hour drive to Atlanta. Thunderbolt has a few options if you need to get work done, but not that charming or quiet. Thunderbolt Marine has similar capabilities to Jarrett Bay. Sail Harbor would be your lower cost option on Wilmington Island, and near the ICW. No fuel or Pump Out, but a small yard that can get things fixed for you. several liveaboards. Good marine store infrastructure here and River Supply in Thunderbolt. We will still be in SC at that time, so PM me if you are headed North. hope that helps.
