Location For Big Teen B-Day Blowout

My Friend Rachael and I are planning on throwing a big combination 16/17 b-day party for ourselves in three months and we're having trouble finding a place to throw it that meets our budget! We're also planning on have one or two local bands play @ our party (we've got one so far) so we need a place that will hold 2 bands and a bunch of high schoolers! HELP US PLEASE!!! Of course we need a place located in DuPage County, IL.
