About to be married !

Dede
So this is the story. I'm about to get married ,and I want to do it at the city hall (I think that's the name of the place people go to get married? ) and after being married my husband would be filing my papers. Can someone tell me how to get this done? ( I don't want to go through a lawyer , too expensive) . 
Does anyone know the contact number for the court house in queens?
