Looking for an emergency vet in the Beacon, NY area

I was hoping to contact someone in regards of finding an emergency veterinarian that anyone may know today on March 16th being on a Sunday, since my cat's eye is closed up? It is the first day it is closing up. I was wondering if you knew any emergency vets who may be able to work after 12pm today and able to bill a client later for emergencies only? I live in Beacon, NY and looking in a 15-20 mile radius for a place for my cat. I do not have money nor a job at the moment but am able to pay a certain amount a month. Whom may ever be  able to bill per month in emergencies like this? She is 16 and I am not looking to euthanize her. She is has been in normal cat standards (very fickle and dislikes doctors, groomers, or anyone giving extra TLC to her). She enjoys life, and I believe she acts her age. 82-83 in cat years. (like any other human that may act a certain way at a very high elderly age) and still the same old cat since I've had her at 5 weeks old. She's gentile but doesn't like to be fixed up with procedures or even when I take her to the vet once a year nor does she like me going with a wet clean wash cloth to get it for her anymore. She is also an indoor cat and may be because of her dental needs.
 Thank you,

It seems like a Google search online would be a good place to start.  I just tried and came up with this:  http://www.rooseveltvetonthehudson.com  It says:   We believe that no pet should go without necessary preventative health care due to costs. That is why we are proud to offer certain important services at discounted fees.

It also says they are closed on Sunday but there's a number you can call for emergencies:

Good luck getting some care for your kitty!!

I found the same one as BetsyGee. Looking for others.

Same Roosevelt practice, but these ones may be sister clinics in Brewster, Newtown and Bedford Hills : http://www.rooseveltvet.com/emergencies-and-after-hours-care.html

(Note: If one clinic is not available, you will be directed to another)
