Recommendations for a custom steel device order

Hello, I am a straight male Dominant that is self-chaste for periods of two to three weeks before I unsecure myself. This cycle repeats all year long. Five years ago, I decided to purchase a custom chastity device and currently own 3 unique cages. Since then, I have not worn any generic or mass-produced cage. The purpose of my post is to see if anyone can lead me toward a company or team that creates custom steel devices. Currently, I possess custom devices from Steelwerks Extreme and Red Chili Chastity. Please recommend other companies/teams aside from the two listed.

• I need full customization authority. This includes but is not limited to: odd measurement lengths down to the millimeter, high quality stainless grade steel, multi lock/screw option for security (1 screw vs 2 screws vs padlock, etc).
• I have found several other sites that offer high quality and highly aesthetic devices, but they cannot custom make a ring that fits me.
• Price is not an issue. Thank you, Mr_Sir

I'm really surprised that you can't get what you want from Steelwerks or Red Chili... but especially Steelwerks. That place has a custom machine shop, and does some fantastic 3D milling in stainless and titanium.
