Seems like a fascinating and extremely challenging undertaking. The most obvious question is whether you have the skills or access to the skills to design a device at that level. AFAIK it would require a team of specialists. Going beyond that, would it be possible to validate the design using FPGA or ASIC? How are you confirming the market reach and size? Since you are looking at a multi-million dollar investment, investors would want to see credible ROI. The execution risks appear to be substantial. That is, unless you have capabilities far beyond those implied by your questions. To answer your last question. I fail to see any better option than the USA. Of course, there are numerous potential legal hurdles depending your current country of domicile. As a minimum you could hasten to Silicon Valley and start building a network of connections. Perhaps there are others on HN who are in a good position to assist.
