Now Casting is one of the Best Casting Offices in the area. It has an online forum where actors can post pictures, their resume, and submit themselves for auditions-- all of it digitally. It's much more affordable than other websites such as LA Casting, and it's less well known so the competition isn't quite as fierce. Of course having great headshots is key and submitting regularly will increase your chances of getting auditions. A good place to start is in the student film section.
