No! You should NEVER pay an agent! When you book a job they take a percentage of what you're getting payed. Let's say you are getting payed $500 to be in a commercial.. They usually ask for about 20% so your pay check would really be $400.
Well, your agent sends you jobs over email and you say if you want to submit or not. If they do submit you the casting directors look at your headshot and resume and if they like you they call you in for an audition. If they like your audition, you book the job (:
Ohh! Gothcha (: and I have been great! Just writing, writing, writing (: and I'm getting my braces off very soon so I'll be able to book more things (:
