You need to start off with some research in to how many people ( mainly local ) would be keen enough to use the site regularly ( aside and including share cost considerations) and how much they would be prepared to pay for the privelage.
You might need to have some system to charge non-members to use the site to help cover costs ( if thats possible). Having a permanent site opens up possibilities of a full time caretaker and perhaps a serious internet connected telescope which would be another way to help cover costs and develop the site. Overseas visitors could pay reasonable money for southern facilities.
Perhaps and IIS poll would be a good start ?
I know the Buckety area is not very flat . How much usable flat land is there for developing personal observatory sites without major earthmoving involved ?
I don't see why power couldn't be produced from solar and wind 24volt and meet casual needs.
I have a dormant 24" f4 binocular project that would be re-awakened with somewhere to house it.
