College student trying to move the city (NY).. LONG-TERM

I am a college student trying to move to the city (NY) from White Plains (not sublet..but long-term)..After looking for a place for months and months I can not find anything that is not a *scam or anything that is *affordable. Unfortunately the commute is getting costly to go to internships and other things in the city and it takes a long time.

Everything on craigslist seems like a scam so I do not even want to look on there anymore, although some people say they have found good deals there.

I know that I need a roommate but I do not want to room with anybody that just does anything because I am very mature and professional for my age and want to find the same.

Can anyone tell me where to find some apts. for under $1000 or possible roommate options?
If any one else is currently going through the same situation or will be able to help me out please reply..

Thanks for reading and have a great day!
