NPC specific textures/shapes/accessories like VSVillage or OutlawMod?

[GendR]

so I've been attempting to create traders for my server that help with the early game economy a bit. I have everything done EXCEPT I cannot for the life of me figure out how to make the different types of vendors (miner, blacksmith, lumberjack, fisher, etc.) have specific items. I've looked through VSVillage, OutlawMod and some other stuff and can see the different folders, where certain things are called for but not within the trader file itself. Bit confused as to where it calls for these things so I can define exactly what I want each specific trader to look like.

Please help
