They're all basically the same. You're probably looking at a custom order, so your best bet is to hop on Google and see where the nearest builder is. You also might be able to get a price quote online if you take accurate measurements of your amp.
Don't know if they make 'em (check with Gator), but since it is so small, I would just go to a local shipper and have a tough plywood box made, maybe some metal brackets on the corners and a metal handle...w/ 1" rigid Styrofoam lining the inside.
