Hello, i'm looking for good methods of making gil, my physical rank is 20 and the most gil i've ever had is 120k i've been told that's not so good so i'm looking for ways to make money, the way I have before was mining, selling everything from what i've killed to NPCs and quests, i'm not in any way begging for any and I don't want any donations I prefer working for my own gil, thank you in advance

All my crafting levels are 5 and below i'm willing to train them to a good rank to make gil, just need to know what rank to get them to.
