How can I make GIL? HELP

Raise your DoH, DoL, and retainers, DoH to craft items, DoL to collect items, Other retainers jobs to hunt for items. Also keep your retainers sales max as much as possible they can sell up to 20 items. Study the market and see what is hot and focus on that. An alternative would be using your tomes to purchase HQ items for crafting. Just study the market before hand.

As an alternate you can do map quest as well, you can find maps with DoL and get a group for treasure hunting.

Leve wise you can see what items are used and craft those as well just compare to market before hand.
