Replacing Internal Doors

I'm looking at getting two internal doors replaced as they are damaged. They are timber veneer hollow core doors, 720mm and 770mm wide.

What I'm after is someone that can remove the door hardware from the old doors and install them onto the new doors in the same positions so that I can just hang the new doors up and they fit perfectly in the hinge locations and the striker plate.

Does anyone know of any places that can do this? I can supply the doors, or they can be supplied by the person installing the hardware. I will be staining them myself.

Thanks.
