Activity for Future Mrs. Goss

I live in Dayton, Ohio. I've been looking at parks, venues, ect. I'm trying to find an affordable venue to hold the ceremony and the reception. My ultimate goal was to have my ceremony with a gazebo so that's really the main thing I'm looking for. So...

Where can I find great dresses for even greater deals!?

How can I go as cheap as possible? Any DIY ideas are always welcome. We're having a evening outdoor ceremony and an indoor reception. I love the vintage rustic look. Any ideas at all? All and any are welcome. Was hoping to only serve hors d'oeuvres...
