Hey there, and thanks for reading.
Moving to a new city and trying to get established in the film circle is always a daunting task. The first thing I would say is reach out to everyone you know in the LA area that works in film/TV and let them know you’re moving out and would like to get some experience on a set. Keep in mind though…desperation is a stinky perfume, so try to be a little more casual about it while still maintaining a sense of professional eagerness.
The best online resources I can guide you to, really, would be this amazing blog by fellow film blogger, it’s called the ANONYMOUS PRODUCTION ASSISTANT’S BLOG, and it’s quite fantastic for people a little more on the green side, there’s also a ton of job procurement links on the right side of the page.
I hope this helps, and good luck! Keep your chin up, and don’t give up.
