Alternate Everquest

I have a young rogue who wishes to learn the art of poison making and use poison pots for a little extra dps but is struggling to find a good merchant
Here is a few possible ideas to help
#Have a dedicated poison merchant with lots of supplies
#Have pre made poison pots drop for mobs
#A newbe type quest with a clicky item that makes poison pots (can be upgraded at higher LVL?)
