What are your professions? I started on a server by myself, and have 4000-5000 gold by myself from mining, herbalism, skinning, and questing. I did instances as filler xp between quests. Well, if I have lots of rested xp, I do instances cause that seems to be the fastest way to burn off that rest xp

If you strictly run instances, you won't make much money until you get to Strat and higher.
