Toroidal Transformer Cover

I've searched the rest of the forum including other threads that asked the same question but can't find any information about where to source the round cylindrical enclosures for a toroidal transformer. I know that these are called "deep drawn enclosures" and all the manufacturers that I've contacted are accustomed to huge quantity orders and want a king's ransom for one or two units. Where are people locating these at a reasonable cost? I'm located in the U.S. Thanks.
 
I used a PVC pipe endcap for my latest project... not too worried about shielding - wanted something that could be mounted without a plate underneath.

Here is what I did.
For fixing the vessel, I put 3 holes on the bottom near the perimeter and put nut-bolts to the chassis bottom. The torroid being curved at the outside has gap at the bottom.

I just placed it in the container and put some support with heat tolerant materials.

For fixing the cover, I had these straight ss plates with two threaded holes that were used to support transistors onto the heatsink. Just put one hole on the vessel and another on the lid.
