Best Places to Look for an Apartment?

Hi, just found out my longterm lease isn't be renewed (and it expires the weekend of my wedding). I am pretty frantically looking for a new spot and was wondering if there is anywhere else I should be looking besides streeteasy, craiglist, and renthop? Also if anyone knows of any quality 1-2 bedroom apartments available under 5k for June move in, please message me. Thanks so much for your help.
