Who makes good oil pans for the SBM?

I'm getting close to needing an oil pan for my R3W7 project. I've spent some time looking around and haven't found anyone that can/will make a pan. This pan will more or less need to be custom, and probably aluminum.

I've found some custom fabbers, but they're not set up to make SBM pans.

Anyone know of a good shop that is up to speed on these? I'd prefer not to make my own...
