Contacting DSO Quad Enclosure's Designers/Manufacturers

Good day All,
I was curious as to how I can contact the firm/designers/manufacturers of the DSO Quad’s enclosure? I really like the design and would like to do something similar, but my product would have different I/O, etc as it is a completely different application. Does anyone know who I can contact to find out what the upfront engineering costs are as well as production volume requirements? Sadly, making these types of enclosures here in North America would be extremely expensive…
Thanks in advance!
