Repairman to move a claw foot rob and fix the drain.

Hi everyone. I’m looking for someone to move a clawfoot tub, pick up the floor to fix the drain and then reposition the tub. We were trying to lay a new floor, and somehow improved the tub enough that the drain is leaking, and the plumber says the only way to fix, is to tear up the floor underneath the tub. If you have recommendations, please send them my way. I’m really happy with my plumber, but he won’t take up the floor. I think that’s pretty common. Thx.
