I just have to say just keep plugging along....it took me 2 1/2 to find a position in my field and that was after my job had laid me off, so it was not like I didn't have experience in my field, in addition to some other training and skills that I've acquired over the years.
This is just to say that the job market is tough, but hang in there, it will happen.
Also depending on the city that you live, you may want to try
Craigslist also, their "hub" is san francisco, but if you look to the far right of the page they have various city links, I didn't recall seeing that on your list.
