If there is some geographical last mile type issue to bring internet to these buildings that are surrounded by fiber, it could be helpful to pitch the church/hospital with a wireless link from one of the fiber pops. I have brought service to medical and hospital buildings in this way before and it's always worked out well.
In the case described above, the topography is "completely flat", and the internet provider in question already provides electrical service to the premises.
That should mean they have public utility status, access to public poles etc. It would simplify such a solution. I've deployed such links in a flat scenario as well.
