Well, as far as this site is concerned at least, you can go to the "Dating & Friendships" area (use the "Forum Jump" menu, bottom of this page, right hand side, to get there). I think you can post personals there; maybe there's someone else out there in your neck of the woods who's seeking something similar.
"As for where to meet poly people, if by some chance you are interested in anything alternative like renaisance fairs, goth culture, sci-fi conventions, indie music, bdsm, or any small fringe group, you will be more likely to meet people who have at least heard of poly and are accepting of it."

Even if it's not an "alternative" type group, if there's a club or something in your area that does something you're interested in, you can always join that group and it just gives you a way to get out there and meet people. If you just meet someone on a platonic level and get to talking about poly, they can decide how they feel about it without any "pressure to agree." Then if they do decide poly doesn't bother them too much, and some kind of romantic connection subsequently develops, you'll already have "had the poly conversation" with them.
Don't know if this helps. It might be a place to start.
