I haven't been in Dunham's lately but they used to carry a couple of long hard cases that would easily work. Not expensive at all.

I wonder if Pelican Vault line would have something to fit your needs.

Pelican a two gun. It is large and heavy enough to have wheels. I had one but sold it a while back. You can custom cut the foam interior to whatever size fills your need.
