How big is the project? Have you looked at running your own fiber? I imagine the residents wouldn't mind not having to manage their own WiFi...
At present we are three owners each building own house, we have 5 different people interested right now joining us to build their homes and our planning is no more than either 50 quarter acre or half acre lots which will let us leave about 15 acres untouched.
The real short term is just Wifi, with ethernet cables for the further homes. Once we get more people, we will look into fiber for everybody.
