You can either choose one of our friends here from the above sticky thread that are known to provide excellent product and service, or post a thread in the Services Wanted thread in the knifemakers area of the Exchange. You will likely have to send the maker the piece you want the sheath made for, for proper fit.
Any specifics, including pricing should be discussed off the forum by the media of your choice.
