Looking for Commercial Foam Shredder in Clarkston, Washington For Sale

I am looking to use, not buy, a commercial foam shredder. I have made many calls and cannot find a business (upholstery, mainly) with one. I am willing to pay a fee to use it but would like to have quite a bit of foam shredded into small pieces for some projects of mine. Please contact me if you have one and are willing to either shred foam for me or allow me to use it.
I live in Clarkston, WA and can get to Spokane or somewhere in Western Washington.
