There are some money-making tips in this guide:

It sounds like you're in decent shape regarding money, though. Once you're too high for EC, you have plenty of options. Can hit up Oasis, WC, or North Karana, for instance, to solo. 14 is a big level since you get Root, which lets you root-dot, which will be your most effective method of soloing until you hit 60 and get Torpor. Target humanoid/undead monsters in particular as they tend to have better loot to sell to vendors.
Once you get a couple hundred plat saved up, a good thing to invest in would be 5/55 rings (made by enchanters, these give 5 AC and 55 HP - they are Platinum Fire Wedding Rings). Beyond that, you'd want to look for +HP, +WIS, and +Mana gear. But the kind of gear you can get on your budget (other than 5/55 rings) won't make a huge difference anyway. Root-dotting is not exactly gear-dependent. Just hunt in outdoor zones and have fun.
