-Farm the dungeon on map 1 for 1-15 PvP gear
This is a great guide.
One comment I have is that the dungeon on map 1 (Cornwell Ruins on the light side) is usually very crowded. Plus the drop rates for 1-15 PvP gear there is actually not very good, at least for Noble gear that will actually sell for around 500K to 1 mil per piece. So while farming there is a valid suggestion, you'll probabaly get gold faster farming spools, cores, or even golden apples.
Also, I agree that really it's actually faster to just level your toon to level 40 at least, maybe even level 50+, so that you can farm duals and powerlevel higher level toons faster.
