For anyone who wants to use the new NPC system (lua based NPC's) proposed as a pr at current master branch (included in the upcoming 1.6 release)
I'll help you re write NPC's or create from scratch based on a detailed outline into the new NPC system.
There is 2 ways on how to request:
1) You post a file and I'll just 1:1 transfer it into the new system. (xml and lua file)
2) You write a very detailed version of the npc and what he should be capable of
You have to be prepared for them to be public domain, I'm not posting them in private and they will serve for other people as examples to understand how everything works.
For those who are interested into implementing this npc system into older tfs versions, here is the summarize of all commits which need to be applied:

Let's start off with something very simple, just a Merchant in different versions
I'll try my best to make some good commentary with showing some visual

-- sets the radius on how far the npc can move away from his spawn position
