I have access to a Machinist shop that might be able to produce this in a limited quantity.Please above all else use 100% certified Stainless Steel produced in USA steel mills.
Don't go cheap and use Chinese-grade stainless it is absolutely horrible in quality. I've seen it corrode faster than any low quality carbon steel made anywhere in the world. Plus it can not be milled successfully into any complex shapes and/or extrusions. It essentially is the worst example of Steel sold into any market today. They usually sell it to cheapskates and scumbags for quick money.
It's far easier to work Stainless with cutting gear that is all made in the USA, and I do know for a fact you guys still make, cut and use Stainless Steel through out your consumer economy. US-made steel is quite good in quality and strength so please use that and not any foreign made garbage passing off as so-called, Stainless Steel.
For me cost isn't an issue but QUALITY has to be 100%. With no short-cuts taken.
