Two other easy suggestions.

1. Take advantage of your retainers. I would guess you have them set to adventuring classes, so check which items they can bring back for you versus the market on your server. You might be pleasantly surprised how much some of the crafting materials they can grab sell for. In this case, im specifically referring to the 1 hour hunting ventures where you can assign what items they will bring back. If your server isnt supporting good prices for anything you can currently get, you can send them on the quick exploration ventures instead for a random shot at something great or potentially something utterly worthless. And of course, the longer explorations for when youll be offline for awhile can yield some good results too.

2. Are you using your Lores? A quick character search indicates that you have several classes at level 60 currently. So are you gearing any of them with lores currently/working through the anima for one of them? If your lores are spoken for, then keep doing what you are now. However, if you arent using them and are just accumulating/capped you could buy some of the level 60 crafting mats in idyll and sell them too. If you dont want to do the research to decide which ones to buy, you could always advertise how many lores you have to "sell" and find a buyer to work with.
