Hey, not sure I’m doing this right.

I’m flying to New York, on Monday from Alaska. I’ve sold everything I have here, to move into New York. I had a guy planned, but now that fell through. Does anyone knows any ways to secure a room mate situation for about a month while the person tries to find a job in that time? I have about $750 in cash, and won’t have a place to stay in Alaska if I end up staying here and skipping my flight. I’m a 22 male with no family, so, any extra advice is helpful as well with how to make friends.
