How to land a literary agent for teen authors?

[Kale]

Alright, I'm fifteen years old and very serious about writing. I'm not looking to make a ton of money on my (yes, finished) manuscript, I'm just trying to see if I can get it published... I'd really like to, of course. It's a young adult, dystopian story and I'm looking to see what my best options are for looking for/ landing a literary agent, and getting published. How much does it cost? And, of course am I too young? I'm also planning on using a pen name, so how do I go about using that?
I would go to a convention, but I don't really have the money, or the time for that matter, with school and everything. And I don't really live in a city that's booming with publishers or anything.
