Cost to Mount Antlers

2 questions about a whitetail shoulder mount.

If I have a complete shoulder mount and want to have a set of sheds put in place of the current antlers could that be done and at what ballpark cost?

If I had a set of sheds and a shoulder mount that was "ready for sheds", how much would it cost to mount the sheds and sew up the cape?

You can get Shed Connectors and mount them on a wall plaque like this. You can use the shed connectors to have them mounted on your old mount. I know a taxi I used took an old mount and mounted a set of sheds on the old mount.
