Image Designer. Also add Tailor. You'll be the coolest looking PvP player out there. Other than that nothing will help.
That's like saying I want to kill every NPC Creature in the game. None can. Even the too powerful TKM, Swordsman, and Riflemen have a handful of creatures they cannot solo.
It all matters on not just what you are but what the other players is. They a Master Pistoleer, your Image Designer can kill them. TKM's are easy for ranged and Swordsman, but not anyone else really.
Jedi can kill most all but that is a long path with its own dangers. If they are a High Level Jedi you're gonna die so read the first sentence as at least will dead body will look good.
Find the job you want to do and hunt the players that you can kill. Though personally I'd just hunt purple polka dotted Kryatt Dragons as at least on my server there's a better chance of seeing one than PvP.
BTW he will not be PvP only. You cannot earn XP and skills or anything useful from PvP so you will be doing NPC battle more than anything else.
