Help? Sweet 16 party :)?

I live in Greeley Colorado & I need to know how much it would cost to rent the University of Northern Colorado (UNC) Ballroom? I'm having a sweet 16 party next year but I need to book the place now before I have to change everything. I tried looking it up & I didn't find anything that told me how much the cost or deposit would be to rent the Ballroom for one night. Help somebody? Please? Thanks :) ♥
