It's good that you found this out early and even better that you know what interests you. To get paid for doing what you like experience is key. Here... are my suggestions based on your answers:
1. Start volunteering to help out planning school events or start interning/volunteering at event planning companies. Companies rarely turn down free help. You get the experience and may develop relationships in the process.
2. Speak with your guidance counselor as someone suggested and see if they can point you in the right direction.
3. Commentating is in the communications field (start taking some courses at the college or some public speaking classes off campus. Also getting involved with school radio and television department (if they have one may be useful). Also volunteering/interning at your local news/radio station could also help you get the experience.
Good luck. I hope it helps. more
