As a former Los Alamos resident I wish you luck in this endeavor, but my guess is Los Alamos is probably too small to run a cost effective ISP operation. My recommendation is to approach this from a "how do we bargain with ISPs as a single unit" perspective, not a "how do we build and operate our own network" perspective. My apartment building in Seattle just converted from cable to fiber. We're only 200 units but it was still enough of a prize to get some competition and concessions out of the vendors, and collectively LA has 50x those numbers. If you can get even 2 vendors to bid on a contract for the whole city then you may be able to get a pretty decent deal. Conceivable they'll refuse to play ball because they're scared of the community broadband concept, but at some level they are still businesses and so if the deal makes sense they may take it. Probably still need to hire a manager, but the expertise to look for is how to manage vendors and negotiate contracts more than "Cisco advanced certification", and you may be able to hire them initially as a consultant instead of a permanent employee.
