Ok so this is only a tiny bit of gold out of this but im sure if you kept doing it would get better money also you get more money , the higher level you are. Not sure if this is a repost.
Ok so go find a group for an instance and as your all on your way summoning etc ask your group for some money for repairs and when they have give you the money pretend to go fix your stuff and voila you have gold so if you are 70 then you get alot more money then you can choose to leave group or do the instance
worked great for me!
