Definitely prepare to be patient! I suppose I can say that my situation is a bit harder, because we're looking for a third out and inside the bedroom, lol.
I've spent some time on OkCupid, and a few various other sites that have really done nothing for us. I've made some new friends through okc, and I feel like through your friends is the best key point. We've had luck with one of our more open-minded friends. But, you never know where interest will strike with someone! You might get luckier then we have! Good luck!
