Aftermarket for container doors?

I have a 40 ft high cube container that's being made into a kennel. I want to remove the doors and build wall on the end with conventional door. If there's a market for used doors I'll be careful taking them off, if not I'm firing off the torch. Anyone know??

There is a market for everything, you just have to know where to advertise.

407 gun club has a bunch of containers end to end w/o doors. Might call them.

Getting back in the bird dog business? Please share some photos of the kennel build.
