Unfortunately, there are many scams geared toward vulnerable beginning actors. In larger cities, you're more prone to find scam agencies or management companies that offer representation for a fee. Remember: You should never have to pay for representation. Ever. A good agent or manager earns his/her pay by finding you work and taking a percentage (usually 10%) of your earnings for that project. The only thing that you should be spending is your time on developing your craft. Any agent worth his/her salt will recognize that when s/he sees you.
