Well, looking online you have two main options...
Polymatchmaker.com is the main poly-only online dating site.
OKcupid.com is a poly-friendly
online dating site, though definitely not all-poly.
Also, look for the local poly community.
Here is a post I made a while back about poly groups in North Carolina: http://www.polyamory.com/forum/showp...5&postcount=50
Basically ncpoly.org is the main state-wide email listserv. Also I believe the Timberlake is near the Triangle metro, so check out the Triangle Polyamory Meetup (meetup.com/trianglepolyamory), which is a pretty active group these days. About half of their events are in Durham, which should be about a half-hour or so drive for you, I'm guessing.
Good luck in your search!
