Here is a list of services that he does, but I really advise folks to speak with him. He is a great guy to deal with and does not mind discussing work (and stuff in general). I have used him before and was pleased, but I think he is now more in demand than ever. After browsing his web page I realized his wait times have gotten quite long. Maybe since I used him before and had a nice conversation with him he readily took my work. He is also giving the gun a good once over. I would give him a call and explain your needs.
