Hi, I am not a maxed player, I am above lvl 90 in all combat skills but I wanted to know if someone can do this quest for me.

I want to know:
-the price
-wich method I can pay?
-the gear you would like to have for the quest
-if you need access to my bank
-how much time does it take you to do the quest
