I hear Vandy Vape is doing great things with other people's designs, you should check them out! haha
No, don't do that. I'm just being a dick. Vandy Vape supposedly stole the design for the Kylin Mini from someone without giving him credit. I wouldn't suggest going that route unless you filed for a patent on the design first. Once you file, I think you're protected even through the patent hasn't been issued yet. Don't quote me on that tho.
If you decide to have a local machinist make a prototype, be prepared to pay a lot of money if you want it done correctly. Machine time is very expensive, especially when working with stainless steel.
