Please don't let him suffer. Take him to a vet, explain his situation - AND yours, ask sympathetic neighbors to help chip in some $$$ - ANYTHING but continue to have him suffer.
It would be hard to think a vet would turn you away and not treat this poor guy! They can probably work something out with you.
Also, your vet could also have ideas about local shelters/rescues that could help defray the cost.
