I doubt any such data exists, but I wonder how many fiber miles and customers WISPs turned up in the past year as compared to some high-profile goalpost... Google Fiber or Verizon FiOS or AT&T Gigawhatever or... Obviously not 1:1, but WISPs as a whole compared to the titans.

I do expect that we will get more customers than just 10%, but the solution might become too expensive, if I have to pay all costs upfront years before I have any hope of that many customers.

I can provide you some advice from a local person in my area that is doing this, while homes aren’t of such a nice identity of 10 meters, they place a pedestal that has capacity for 96 count splice trays at every 3rd home. You can use something like a flat drop cable to be buried later as that connection. They may also drill up to the home or use a maxi or mini-sneaker type device to directly place the duct in the ground from that pedestal. 

The bonus of this type of solution is in the winter months where the ground is frozen you can often leave this cable on the ground to be buried at a later date. I helped a local WISP turn up their first fiber link in the past two weeks and this was the strategy they took.
