If ur trying to make gil to buy equipment/gear the best thing to do is to just quest, and if ur thinking theres no quests available then ur missing something. There are so many things to do in this game and so many ways to level up early on and especially on your first class its ridiculous. Personal story, class story, open world quests, guildhests, guildleves, hunting logs, dungeons, and fates all offer ways to level up and get gear. There should be very little you need to actually buy if anything at all.
This one time at FFXIV camp I tried to get a 3 person party going, but just ended up as a Disciple of the Hand.
