Where are the hardcoded (non-MB) gold "faucets" in FFXIV?

You shouldn't need to buy equipment for leveling your first class with gil, ever. Not only do you get constantly new equipment from the main story and other quests but you can also buy equipment with poetic stones at level 50, 60 and 70.
The only dungeons in Heavensward requiring an item-level are the level 60 dungeons. You can and should have done your jobquests by now which gives you level 60 equipment good enough to clear those. Better yet, go to Idyllshire and buy Shire gear with poetics (ilevel 260, upgradeable to 270).
