Sorry, but an idea, no money, no experience, no connections, does not a 'rare, once in a lifetime opportunity, up for grabbing' make. I would suggest that you seek out seed money before looking for developers. Alternatively, you could take three months or so to go through one of the many development bootcamps, and pick up the skills you need to build your own demos and also the technical knowledge you'll need to vet candidates. It's also a great place to find hungry, scrappy folks who like to code. Also, drop the NDA. At this point, it just shows how inexperienced you are. If the idea is so powerful that you are afraid it will be easy for someone to run with, don't share it with anyone - make it yourself, and keep the success for yourself :) Good luck.
