Crystal sales are always good starter income, and nowadays there are some decent drops in brown treasure caskets that spawn randomly. Sometime you even get a rare item worth a fair amount (very rarely, but they do exist).

If you are lucky, mystery boxes kupo power will be active. I was running out of inventory space with all the armor I kept picking up. I'd keep a set to wear, and npc the rest, just from the initial run of zones (gustaberg, K. Highlands, dunes and pashow or their equivalent areas). Depending on the gear, it would NPC between a few hundred and almost 2k. More than enough to buy most spells for rdm 1-60 (farmed the ice spikes scroll), increased my gobbiebag, and pay for blu AF. Nothing close to rich, but it is enough to get me what I want to do what I do. Sparks basically eliminate the need to spend gil on weapons. Don't underestimate what some people will pay for stacks of generic items you get while killing low level mobs. And don't be afraid to put up stuff that has a 1000 gil price history. It most likely sells quickly, and you could possibly list new stuff 2-3 times a day depending on your playtime. It can add up.
For evidence, I cite my ffxiah history. 193 transactions since May 9th. In two months, I've spent 986k and sold 775k. Closest I came to purposely farming for gil was selling stacks of gausebit wildgrass for 30k. I knew this sold for a decent amount, so I purposely xp'd on flys in Mer. Mountains, making it a double goal for the day.
