[NPC] Will trade only if quest is finished.

[Shadowsong]

Hi. I need a NPC that will agree to open the trade window only if player has a certain storage value, else the NPC will refuse to trade. It's something like Rashid of RL Tibia, but without all his missions and stuff.
(I btw, have looked at a rl-like Rashid script and couldn't understand how to do this :\)

I'm using TFS 0.3.6. crying damson.
