So Ryan, what kind of Event are you doing? What is the event all about? Where is your audience located?
These are all things that you have to think about when promoting and marketing your Special Event.
Here are some basic tips to get you started:
1) Create an announcement of the event (so a press release is a good thing) at least 2 months before the event. If this event is for a charity, then most newspapers will run it for free
2) Get on Facebook and create an event there and invite all your friends. If this is going to be a yearly thing or a monthly thing then you might want to think about creating a fan page and get your friends on it as well.
3) Call all the local Cable TV stations in your area, see if they would be willing to at least have you come on once to discuss your event
Good luck! Hope this helps a little bit!
