Consider including a shot that shows your natural apprentice too. Professional level headshots can be expensive and range anywhere from $400 - $1,200 (US Dollars)  Be as natural as you can in your headshot, and avoid over-editing or makeup so the casting director knows what to expect when you audition.

Agent workshops or showcases are opportunities for actors to showcase their skills in front of casting directors or producers. Actors attend these workshops and do read scripts to potentially land roles in the future. Make sure that when you attend one of these workshops you’re dressed well and you’ve prepared a monologue.
