I have been is the same boat trying to get the career moving. I moved to LA in dare I say out of a bit of desperation. Upside: I shot a short film in the area and had great access to talent and crew etc. Downside:I had very little luck in finding production work. For my last project I posted an add to hire a grip. I got 54 responses in one hour. 54. Having lived in NYC and LA I can say that one should not be attached to a location. I think it is more a function what your vision for your career is and if you can focus on that with out any angst or stress.
