If you have even the slightest scrap of talent, why not get out there and get an agent? A talent agent, if they are really good and actually legitimate (many, many are not), is like your fairy god mother or guardian angel, finding you great opportunities and working hard to get your name and face out there to casting directors and production companies. A certain agent may send talent out for very big parts in huge productions, others specialize in smaller parts and represent more clients overall.
An agent may not necessarily be concerned with what your talent is, they may have different priorities like looking for certain types that casting directors have a need for. An agent is really the middleman between you and the parts you are looking for. Talent is what you can do, what you're good at, but also a general term used by those that use you for any and all actors and performers in a production.
The agent who represents you is dealing with people who see you as just that, talent. It is a commodity, a product that they either want or can't use. Talent, agent, the two would otherwise not be related in any way. Who you are is really not important, nor is how good you are. The agent is concerned about careers, theirs, and the people they work for. You come in to the equation as talent, if it is seen that using you will help further those careers of the people hiring you. The cold reality should be a relief once you understand that you must rely on your own determination and courage, not the good graces or professional obligations of someone else to make it. There are talent agents out there that will do right by you, just don't leave it all up to an agent, any agent, to make your career for you.
