Wedding Flowers St. Louis Mo

Ceremony Locations Cheap-St. Louis?
Looking for some areas, less expensive to have my wedding ceremony. I'm in St. Louis, MO and here, everything seems very expensive. I want a small ceremony, more than 75 people. I would like on or near the STL. It would be nice to have it out where you can have green areas and flowers. MO Botanical Garden is too expensive though. Ideas?
