I think the post of Ms. Critique is not so relevant to your question. There are single girls living here in Lakewood, often working where there are other girls they can socially connect with.
You will also find a lot of girls in Brooklyn, maybe more shiurim to go to there. There are also a lot of opportunities to do Chesed in Lakewood, which helps you begin to get to know people too.
You have to start with some connection, job or friend you can go to for Shabbos or something in whichever community you will choose.
Much Hatzlocha to you.
