Convention Plaza in Irving was $4000 for an event (relatively cheap when compared to hotels, etc.). It has a dance floor and a stage area and can seat up to 500.
You can bring your own alchohol/bartenders, but they require you to use their security if alcohol will be served.
Try Northeast Wedding Chapel they provide the facility and you bring in your own catering,alcohol and bartenders. It is located in Hurst off of Precint Line Road.
Hope this helps
