Can’t add much to the excellent suggestions already except you can try contacting the FCC and see if there is a provision for getting licenced for a very low power station to cover the area you mentioned. Since no other station serves the town you may have a shot. I know in Canada such a thing exists.
A five watt FM transmitter you can get on ebay from China costs under $500 and just needs a simple 50 ohm ground plane antenna obtainable from ebay,and this would cover the whole town.
