Best proffesional/secondry profession for begginer

Ive jsut purchased factions after not really getting that far in propehecies (im lvl 12, but its a bit hard, im going to continue it though). Now i have factions i want to build a character that can solo farm areas well when i get to lvl 20. Ive been told a warrior/monk is good, but is there anything betteR?

Monk/Warrior...It is expensive to make to a new player(Approxamently 45k in all) ...IF you cannot afford that a W/Mo is limited on solo abilities but is a lot easier and cheaper to make.
