Simple premium npc

[Webtimize]

Hey otland!

I'm requesting a NPC. When you give x item you recieve x premium days.
30 fern = 6 premdays
25 bloodherb = 10 premdays
The name should be "Ashish" and i'll change the looktype myself.

Dialogue;

Player: Hi!
Ashish: Welcome, |PLAYERNAME|! Did you come to trade some herbs with me? I only accept FERNS or BLOODHERBS.
Player: <choice>
Ashish: There you go! Enjoy your premiumdays! |REMOVE ITEM| & |ADD DAYS|
Player: Bye
Ashish: Farewell, adventurer!

I hope someone is willing to make something like this for me.

Thanks!
