Engrave-Carve
I'd like to see a shop where I could have my name inscribed somewhere on the armor for identification or for a bit more hefty fee a design engraved on it. Mostly for bracers and Breastplates, but could also engrave words on the inside of a ring. Quite a bit you could do with this. Have a nifty design carved into that plain walking staff.

Tattoos
Love to see a shop that does these. Yes I know you can write it into your description, but this is for vanity and for those ever glancing people. Simple designs nothing overly fancy could be done. Would be fun to see groups of people forming groups or clans all getting the same design. Once you have one you cannot get another, not including immortal tattoos, nor can it be removed your char is stuck with it for their life.
