If you can sell the cage you might get 80%. Building a new one would be x + any loss from the first one. Shoot for half your replacement cost if modding the cage or removing the door frame an studs an replacing. If you move an the cage goes with you it’s that fee again plus 10%.

But friends of friends an family might do it for dinner. Check all your options before jumping.

Heck somebody on this forum might live close an have skills.

Good luck!
