Cheap Event Halls?

Hey y’all. I would like to host an event/ party in about 2/3 weeks. I’m looking for an event hall in/ near the greater houston area but everything is so expensive lol. About 300-500 people might come. No food needed, just tables (catering food from an outside place). Do you guys know any cheap/ affordable places? Thank y’all so much ☺️

edit: location is flexible but I would prefer the south/southwest/ west region
