I took a look at your location, I would suggest a fixed wireless network backhauled (fed) from Airdrie. There is plenty of choice of scalable capacity there including Virgin Media in some parts.
The terrain appears to lend itself to link/distribution from existing properties from an initial look at the maps.
The only sticking point is you either need a competent Fixed Wireless company to put in a commercial solution for you or you need a competent Consultant in the same industry if the community were looking to put up their own network. Their maybe funding sources for a community Hub approach too.
We did a whole load of planning work for various parts of Scotland some years back when the Scottish Executive were throwing money at fixing problems like these. Guessing it didn't quite work, BDUK style.
Our village of Plains does not have its own exchange it instead uses Caldercruix's which is about 4 - 5 miles away, Due to this it is almost impossible to get more than 1Mb down(I only get 256kb) According to BT we are not getting Fibre any time soon. so is there anything that can be done?
