section 8 question?

ok i live in New York City and as of January I can get Section 8 Vouchers for myself and family! It's myself, my mother and my three brothers! I'm looking for places that have 4 bedroom apartments and take section 8! So we can move because i need my own room! Were in a 3 bedroom now but i don't have my own room! I need some help with this because i really don't know where to look and who takes it here in New York!
