Hey gregn. If you email me the photos I can post them for you, or show you how to post them. Joe Clemente's palms can be found here.

As far a SC native palms, we have Both Sabal Palmetto and Sabal Minor. Saw Palmetto and Needle palms.
Both Sabal Minor & Needle palms should do great in your climate.
On a side note, Butia although not a native grows like weeds down here. You may want to give them a try. I know Barrie has a nice size Butia growing in BC.
