I am searching out how to build a stage. I need to know the costs, and the best type of material for acoustics. I am trying to erect a stage in an old Wal-Mart building that there is in town(we are trying to turn it into a youth community center/gameroom/concert hall). I know it's a longshot, but could you please possibly figure up the stage measurements within this area (199'x 300'). Also if you do do this, please keep in mind that this isn't just a concert hall there will be other things in here too, so it needs to be big but not so big that it takes up the whole thing.
