Looking for a shredder in the USA

Hello, My local Boys and Girls club are starting up a 3D printing education program. I am looking for a shredder for the misprints so that we can also include teaching about recycling. I have sent the plans from this site to all the local metal shops and on averaging they are returning with quotes of around $6,500.00. That is way out of the budget. Can anyone help us out with a better price?

The $6,500.0 was assembled, I could do it myself, I am a contractor at my day job. I asked about just the parts it lowered it to average of $5,000.00 still way to high for the budget.
