Anyone in/around Charleston, SC? Timber question...

[Palmetto]

Greetings!

I'm interested in building my first timber frame project (some timberframe sawhorses), but I'm not sure where in the Lowcountry to find Eastern White Pine?  I found a place in Summerville that does Douglas Fir, and that'd probably work great (based on the bit I know), but if EWP is an option, I'd like to start there.  Anyone know of any places?

This will also be my first ever woodworking project of any sort (beyond whittling the odd stick when I was a child).  I'm trying to avoid getting poor quality timbers, etc.

Thanks in advance!
