Sometimes some places are hiring even if they don't have any signs up, or don't necessarily say that they are looking. Just go apply at places you'd like to work, what have you got to lose? I've gotten calls from places like that before, and you might as well try to get a job at a place you'd like to work rather than just apply at places that appear to be hiring. A lot of the time, places have their signs up year-round regardless if they really are looking for anyone anyway.
