Need Help

Do you know of any good (cheap) place to have a
Reception? Here is what we are looking for:
Reception area in Denver, Thornton, Westminster, Northglenn etc. Pretty much anyplace we can get to in an hour. There is a slight chance we might have the ceremony there too (10-20% chance) and it needs to fit 200-250 people. We are hoping to stay under $1000
And are open to anything (community centers etc.) we can be creative. Any help you can provide would be greatly appreciated.
