TV + Macro + Make Bar... Make Bar... Make Bar for 15 days straight.

As Caimie said it took me around 160-200 leves. But 80% of the rest was just super hard core bar/cloth/leather/food grinding. Its INSANELY boring but very efficient since you get your money back (or you use the materials up). Note I attempted to HQ each getting the 300% XP bonus. But quick crafting would be faster XP grind at the cost of much more material consumed (and mostly only getting NQ results).
