How close is your nearest business that provides free WiFi hot spotting? If its line of site and less than 2 - 3 miles a good high gain directional antenna will do it for you.
Or, If you're lucky, you could also pirate off any of your neighbors, that don't have their home WiFis locked until you get caught, with such an antenna.
Otherwise you just have to cut all the crap services out and reduce your bill down from $250 a month down to the bare minimum services like I use. I have basic phone and mid range internet 50/10 Mbs package with nothing else on it.
It costs me about $60 a month unless I do a lot of long distance calling and I can get all the TV I care to watch through my Roku now which is free, beyond the ~$75 I paid for it on Amazon as a second top end factory reconditioned unit.
