Disabled Professional Willing to Pay $$$ for Custom Work

Although I am right-handed, my disability makes it easier for me to use the mouse with my left-hand. I would be willing to pay good money for a customized Razer Tartarus Pro Gaming Keypad v2, to make it "southpaw-ed". Ideally, I would like the entire right side attachment recased moved and to the left side, the moved to where button 16 is, and if possible, the ergonomics of the case reversed to comfortably fit a right hand. I willing to pay hundreds for a perfect conversion. Please reply to forum or PM me if interested. Also, if you have the skills and this goes well, I am willing to pay thousands for a re-cased and re-designed PS4 controller I can actually use. But it would be very extensive custom work, as I would need a split-controller, because I cannot bring my hands together.
