Sam and Jim go to Hollywood is a blog with a series of podcasts from two Minnesota based writers who moved to LA and broke into the business. Their podcasts are funny, informative, and detailed as to what the process of breaking into TV writing is really like. Most of us who hope to break in will have to do something like they have done, (and are still in the process of doing).
You don't say what kind of work you're looking for. Most of the jobs available in TV writing are for staff writers on pre existing shows. The formula for getting a staff writer job is basically Really Good Specs + Really Good Connections + L.A. Address.
Most of the TV staff writers I've dealt with directly got started as writers assistants, and the competition for writers assistant jobs is fierce in and of itself. One common path among the people I know has been office PA > writer's assistant > script coordinator > staff writer.
Now, I've also dealt with showrunners who didn't come up through the ranks as staff writers. They wrote a hit feature film or two, wrote a pilot that caught on and the rest was history. That begs the question of how you go about selling a feature spec and get it made into a hit film.
People who've had great success in some other popular entertainment medium can cross over to tv and start on staff, or even create shows, but w/o that proven mass appeal, you have to fight your way up the ladder.
As a practical matter, it's unlikely that TV agents for the LA based industry will even talk to you if you're not in LA. What they're really looking for is someone who has excellent writing samples, original pilots and specs from hot shows, along with a well developed network of people in the industry. They want the network b/c the networks is what gets you work and keeps you in work.
