when I used to have adamantite enchanted I would pay 300pp per stack.

This is what I charge to summon a stack of Clear Vials of Mana. That spell is 600 mana and it takes me about 45 minutes to complete.

All good advices here. Last time I enchanted 10x stacks of brellium for a fellow and he gave me an enchanted dwarven BP for free. But honestly, I didnt ask for anything to begin with, I was happy to help. On the other side, I remember enchanting 5x stacks for someone else, and I barely got a cold "thanks"... I wasnt pissed off but I thought it was a bit rude/ A big thanks would have been better, with some kind words at least.
Just be nice and fair without over valuing that stuff, EQ is better played without price charts, especially on services like that, otherwise it sort of kills "interaction", as people tends to just throw coins in da machine, waiting for stuff to be ready
