The $275 was being presented to the city council and was depending on their vote. They require me to have insurance on my equipment, provided out of my pocket. I also have to cover the light bill for the utility shed/base station. The potential customer base in the city with the water tower would not break 25 on startup so it would be financially tough.
On the other hand, the tower owned by a local is willing to lease me rental space for $150/month because I am a start-up and allow me up to 100ft. No word on splitting the utility bill yet, but the fiber connect is still $50 per 1/1. The only problem would be competing against the wired folks. Charge 25/month for 1/512 entry level package and draw in customers.
