How do I make gil for crafts?

So, HQ low level crafting gear? I'll try.
I hitted lv30 and I have 9000 gil more or less.

Not sure how you have so little gil. You've completed the storyline right? As a WHM with Holy you can mass farm any of the droppable items for massive amounts of loot. Fleece is a good one, not too heavily farmed. There are a few sneaky spots that the sheep spawn. Gather them all up with Aero and Holy them down. Pick up mining and farm shards. People are lazy and don't want to do this. If you have the patience you can make easily 50k gil per hour farming shards.

On my server Lightning shards are most expensive at 70-100 gil per shard. At level 1 you should be able to farm maybe 200-300 per hour.
Watch the cotton prices of crafting gear. See if there are any pieces that are work month and then price out cost of shards and other mats to see if its profitable.
