Most of the folks here are doing small volume work, but perhaps you might get lucky.

Did you try contacting some professional platers? I've seen automated lines and barrel plating used for this kind of volume (and more volume obviously) but hanging a bolt at a time in a tank isn' going to get you this kind of output. You might want to check out finishing.com for referrals and contacts that might get you into this kind of volume. You might need some serious equipment.

Remember also that after a certain level of volume, you're going to have to deal with disposal issues and the EPA. Now you're into the big time and I strongly suggest you NOT try to do this volume in your basement.

Just my 2 cents worth.
