A really easy way to make some extra ffxi gil (especially in the earlier levels) is to do the Justice Badge and Blaze Spikes scroll quests.

First thing you do is make a new character in Windurst. After that character is made, go back to your main character and buy/farm 1 Rarab tail and 4 Wild Onions. Send them to your mule. Now go to where the Star Onion Brigade is (behind the warehouses in Port Windurst). From there, talk to the young Tarutaru on top of the stack of boxes. You will go through a small Cutscene and they will ask you to bring them a tail. Trade them the Rarab Tail after the cutscene is over to become a member of the S.O.B., and recieve your Justice Badge. On my server, these sell for about 10k. From there, zone, come back, and talk to the same Tarutaru to get another cutscene. Trade him the 4 wild onions for the Blaze Spikes scroll. this sells for about 50k on my server. 60k for about 10 minutes of work? Not bad! Now send these to your main character for selling. Delete this character and repeat if desired.
