I suggest you do a search for old threads on the board for job tips and specific NYC hospitals. There is a lot of information on those old threads.
It is still a very competitive job market at the moment in NYC. Are there any hospitals you have a connection at through a friend/instructor/clinical placement? I would put those places at the top of your list. If not, try to build a few connections in your last months of school or find an internship.
Did you attend nursing school in NYC? If so, surely you have some ideas from your clinical placements about where you would like to apply. If not, at least give us a sense of what area you want to go into so we can help you - peds?psych?med-surg?
Being male and 30 sure doesn't hurt.
