Inexpensive Caterers

I am getting married November 8th, OF THIS YEAR...i know i`m crazy. We decided last minute to have a party along with the church wedding we had planned last year. We eloped last year and got married civilly, but we both want to be married by the church so we decided to do so in a small church weddding for close friends and family only. We are having a small party at the club at my job but i need a caterer and don`t have much money not much at all, the event will be about 100ppl...Any advice is appreciated. I am in the NY/NJ area. Thanks in advance
