Drug Rehab / Rehabilitation for Addiction in New York?

I need to find a residential facility in new york state. I tried searching the web, but there’s so much ‘spam’ that I can’t tell real facilities from nonsense..
I have NO idea where to start. Please give me specifics – or real organizations that can provide direction.
Thanks.
I don’t care about private/state… but there is amoney consideration. My mother only gets social security…and it’s not much. I don’t have money to spend either.
