6) Convert extra gear into materia that is no longer needed and sell the materia.
7) Check your retainer and bags for any spare crafting materias that can be sold or crafted to make some quick money.
8) Beast Tribe dailies is a good way to make money and Ixali quests can also help you level up crafting.
9) If low level progress through the main scenario further as it gives a lot of rewards from a lot of quests.

After I take these steps I make about 75k gil by the end of the video and have another 200k gil on the market board to be sold. It's important to avoid allowing your gil to drop too low. It's a good idea to set yourself a minimum as a safety barrier, I would recommend about 100,000 gil if you are a new player.

If you have any other suggestions let me know, hope it helps.
