... there is a legal obligation of any official or business entity to answer the letters (that has been abused by dissidents sitting in GULAG and DDOSing the Soviet power). If such obligation exists in USA, then you could just send all the local providers the registered letters with proof of sending and proof of receiving requesting the possibility of connectivity. Or enter their office and leave there an official letter, demanding a registration number on the copy. This bureaucratic magic makes wonders since the bureaucrats should either answer "Yes, we can" and really do, or answer "No, we cannot" that amounts to false advertising.
I live in similar conditions (suburbs) and have a similar 24/7 requirements. Before I moved I checked for connectivity and there were 2 already working options - state monopoly ADSL and a quite competitive CDMA. Now I have 5 links total - CDMA, ADSL, 2 WiFi's with quite big dishes and a VDSL where I was to hang cables myself.
And the last: You may establish a nonprofit entity that would buy a wholesale.
