The best place to get gold is to buy a gem card and convert gems to gold.
If you have a ton of fractal relics and encryptions, you can buy 30 fractal encryption keys per day and open them. You can then sell the junk for more than what you paid for the keys, and (optional) use your artificer to upgrade the tons of +1 infusions you get, you can get a +10 in just a few days.
One way to convert karma to gold is to buy crab grabbin gloves from Bram Dawnrazer, forge the result, and salvage that for cloth. It might actually be better to buy leather gloves, leather is pretty expensive right now.
If you have ley line sparks, charged quartz, and bloodstone dust, your weaponsmith can make ley line tools which are profitable.
You can gather flax nodes at the Jaka Itzel flax farm each day. Also, there are rich iron nodes near Gallowfields and Helliot Mine waypoints. The potato farm at Loreclaw is very close to a waypoint as well.
