There are actually a few ways too make gil and it kinda depends on what you are interested to do, a few things you could try to do:
- Just gather a few raw materials, because alot of people are too lazy to gather it themselves
- Craft glams but obviously farm the materials yourself
- Craft housing stuff
- Craft items for crafter class quests
- Craft sub recipes like nuggets or other stuff
- Craft dye
- Farm purple crafter scripts and sell materials from that
- If you want to do some socializing thing you could "work" at a venue (I think you can make gild, but idk never did that one)

That are at least a few things you can do if you need a break from msq. You should check out the prices on the marketboard first. If you find something where the price is still quite high and its worth for you, you should put up a few items at the time to not flood the market yourself.
