Business pricing is not just there for the sake of it, it's mostly used to subsidise infrastructure building costs which can rack up in the tens of thousands. You could potentially negotiate with them on the monthly subscription price (for a lower SLA, etc) but I'm sure the main dealbreaker would be the one-time install cost, and not the monthly one. And you can't negotiate that down either, because the people who will dig up the streets have families and/or cats to feed. Maybe what you could do instead is find out if a building to which you have line of sight is already hooked up (or even better, has active service) and negotiate with the owner if they will let you install point-to-point wireless links and possibly piggyback off their existing connection.
