Before I was fully melded for wvr, I mainly farmed fleece, and made wool equipment. I found that to be fairly profitable. I checked the market board to see which pieces of gear were selling for the most and made those. You can generally make 5k+/craft. You can also spiritbond while farming fleece. This was surprisingly one of the quickest ways to spiritbond. There is a group just northeast of Camp Dragonhead where you can gather up a bunch of mobs and aoe them down. I think it's about 10-11% spiritbond/pull on i45 gear without potion/FC buff. I don't know about your server, but Savage Might IV sells for 450k on my server if you're lucky to get one. The crafting materia are also fairly profitable. You can also make your whole left side equipment to spiritbond with wvr.

Another option is to make linen equipment. If you have reputation with the sylphs, you can buy the materials to make the gear fairly cheap. This can be just as profitable as the wool gear without spiritbonding.

I've found that felt stuff doesn't sell so well on my server, but if it does on yours, you can farm the snurble tufts at the Burning Wall and spiritbond, just like with the fleece, but it isn't nearly as fast, and you don't get nearly as many as you would fleece.

I would say the militia gear and the one star stuff is more profitable, but you probably can't HQ those so easily without melding and getting cross class abilities.

I won't say that making the yarn/cloth is bad, but they are much less profitable, so you have to make many more, which takes a lot more time. They are also a lot harder to get HQ because they have 40 durability, especially if you don't have cross class abilities or melded gear.

Mining is also very profitable. Even at low levels, you should check the market board. Some mats sell for a lot because of people needing them to make stuff to desynth. Generally silver/mythril/electrum ore sells for a lot, but it may vary on your server. A lot of stuff can sell for 200-300 gil a piece. If you are smart and scout prices, I wouldn't be surprised if you could make 2k/min or more mining low level stuff. Also, once you hit 50 and meld your gear, you can make much more. I can make 20-30k off some unspoiled nodes. It takes about 3-4 mins to teleport, run to the node, and gather the materials. 20-30k for 3-4 mins worth of time is not that bad. You can get even more if you are lucky with getting HQ stuff. Some of the HQ raw stones sell for 20k on my server, so you can potentially make 100k off one unspoiled node, but you have to be fully melded and have the forager's tool.
