Okay. The advantage of being a writer is that you can have any day job and write during your free time. So, you can relocate out here, get a job in your current profession, and maintain financial stability while building your contacts to get an "industry" job.
PA work isn't really the most direct job for a writer because production assistants tend to be focused on production work. Ideally, I'd recommend (in this order):
#1: Writers' assistant on a show. This is the "PA" of the pre-production world. Here you'll be delivering coffee and scripts, depending on the show you could be in the writers' room, and you'll be in a good position to create relationships.
#2: An assistant for a writer with a deal.
#3 An assistant/intern for a production company that produces television.
For these jobs, like most, you really need to know someone. That's why I suggest you focus on getting a livelihood job, building relationships, and then going after an industry job. ALL THE WHILE WRITING. Always be writing!
