I had a similar problem on a smaller scale.

Look up the document destruction services in town. There are a bunch around. They have trucks that have large shredders on them. They have a schedule and will stop in front of large buildings - if you can be there at the same time, the driver might let you dump the stuff in for a few bucks.

Alternatively, law firms, escrow companies, cpa's etc. have bins in their office for shredding. Maybe you have a friend that works in one. Ask if they can call for a pickup and bring your stuff by - and pay for that month's service for them.
