Early game GP

I did the starting zones (Dun morogh > westfall > redridge > some duskwood) and am about to try out the Northshire zone. Ive been strapped for GP most of the way, admittedly I spent a bit getting my engineering to the level where it required Iron.

Should I be keeping an eye out for mobs that drops decent value greys and farm them or does the GP from the new zones start to offset the amount of broke I feel with 5gold to my name and 7 spells that are 80 silver each?
