hey, im 17 yrs old, my friends got a band going, they like to record their work in the basement. One day my friend calls me up an says he wants me to start saving egg cartons, to sound proof his recording room, or make a small enclosure to record in. I thought it was a great idea. a few weeks later, we were driving down the street, andsomeone was throwing out a HUGE stack of the 1 1/2' egg cartons, so we picked em up. We havent had the chance to set em up, but we plan to clean them up a bit, then spray-paint them to look better, we think it should work. I think that in your case, this type of solution may work. I dunno, give it a try if you like. I hope you find something.
