Stray cat with broken foot

TLDR: Looking for recommendations of budget friendly after hours vets to treat a cat’s broken foot.

Hello, there’s a feral cat I have been feeding for a long while now and he recently has shown up with what seems to be a broken paw. He can’t put any weight on it and I feel awful. I have been planning to do the TNR routine with him but I unfortunately only see him after 5pm as he’s quite the roamer. With the situation becoming more dire; my question is, are there any vets or places that would help this cat after 5pm? Additionally would I be looking at a hefty check? I really care for this cat but I really can’t afford to spend too much money at the moment. I would have no issue keeping him with me but I have a relatively small studio apt and a cat of my own who would not be a fan. TIA
