Xcel speaks wise, as do the other fellas here.
Mate i know how you feel, with 320 hours here i've spent 12 months looking for work. You need to get out and do your best to meet the chief pilots. an email will not cut it (i found this the hard way) Also be prepared to move, i'm planning on moving mid year if nothing surfaces.
Aviation is a funny mistress, you will get work, you just need to tough it out it'll make that first job all the more sweeter.
and what ever you do, do not give up, too many people throw away their dreams just because it got a little tough.
