Basic service fee is 100k for whatever type you want, thigh sheath, harness, swordbelt, axe frog, quiver, etc.
Price includes unnamed skins. You may provide the skins, or I can get them for you for a fee depending on number needed and type. This is because gathering 50 skins of some types can be time consuming. Skins over level 75, you must provide the skins.
Decorations (lacquer, dyes, etc) cost you what they cost me.
