I just wanted to add something else I discovered today. I bought a treasure map, trying out that for the first time ever, despite having unlocked it during ARR whenever I originally was leveling my ninja. Three archaeoskin maps bought for 1,000-2,000g each yielded enough raw gil to cover the cost of the maps, as well as nearly 300,000gil in crafting mats. The value of the loot from the maps varied widely (~30,000-150,000), but provided the low end is the true low end, these are basically free money if you don't have enough stuff to sell already. Also, to amend the advice regarding company seals: I find I make more gil per seal selling the adamantite fransecas (sp) for the relic weapons than raw mats, almost twice as much in fact.
