Most stock makers include the inlet in the cost of the stock. They will need to know the type of action (IE: Remington L/A or S/A) some will ask what the rifle is chambered for so they know if it's long or short. Single shot or floorplate, and barrel contour. Not all stock makers offer every barrel contour, you may have to get something close and open it up to fit. If know what style you like but aren't sure if your barreled action will work in that particular stock, check with your smith, he should be able to help you out. The only other cost would be fitting, bedding, recoil pad, swivel studs if wanted and / or finish if you go with wood or laminate.
