In the beginning of course you may find your own jobs, but as you get a little busier, then you’re going to be working while your agent is hopefully handling future work for you. That’s when having an agent, or an agency working for your benefit is going to come in handy.
When seeking an agent, try to find out what kind of actors that the agency or agent represents and what their type is, as some agencies specialise in primary types of actors, such as the girl next door, tough guy, business man type actors, while others may represent a completely different type.
When selecting an agent, be sure to find out the types of actors and actresses that agency primarily represents or has a lot of. There is a very good reason for this. If the agency you’re looking at represents a whole lot of girl next door types, then you, as one of many of those, probably won’t get looked at for a while for those parts, with so many of that type in the agency.
In your case it might be better to select an agency that primarily handles tough guys, so that if the casting director is searching for a girl next door type, you’re going to be one of just a few clients like that that your agency handles.
The most common way to find an agent is probably word of mouth. Find out who represents someone that you admire, then ask them to speak with their agent or to put in a good word for you so that you get a foot in the door.
The second most common way of getting your agent will be by being seen, so each time you’re in a production, if there is an agent you’d particularly like to work with, send them a small postcard version of your headshot, or send a postcard from the actual show.
Plan to attend some talent agency seminars or check out the back stage papers to find out where those seminars are being held.
Send out blind mailings to the agencies you’d like to work with, that include a headshot, CV/resume and a cover letter.
