Sadly the only way you will make money as someone else put it is leveling a alt or several at that.

Put some cheap item on the market that equals roughly what you alt gathered leveling 1-50 doing quests and have them buy it to fund your main and then deleting them afterwords to rinse and repeat, mind you this time consuming and is not idea but sadly I see no other way you would get a influx of new gil since SE seem to want to be tight lipped or not even acknowledged there is a issue.
