Watch what you spend your money on – if you’re a talent build that is never going to use a particular skill, no one says you have to buy Tibia Gold.
If you want to stay at journeyman level of your profession for a while, go ahead. You can always get these things later, and in the highest levels money is a lot easier to come by Forge camp Farming.
The alternative to Sun fury farming is legion farming at Forge Camp Anger in the Blades Edge Mountains. Instead of signets they drop Marks of Sargarus and instead of Arcane Tomes they drop Fel Armaments. The best mobs here are the Mo-arg workers, especially the smaller ones.
Also, keep an eye on the auction house. Never sell things to a vender without checking the auction house first - you never know when there might be a market.
If you happen to notice that an item is worth over gold on a vender, you can be pretty sure that someone else will want it and will pay a pretty good price for it as well.
One of the most annoying things a new player can do is ask higher levels for money. This is much more likely to get you ignored and possibly challenged to a duel than to actually get you anything good. Don’t bother.
