I did exactly what Onorok Did.

Leather ring is the way to go, its the easiest and fastest way to get skill at that point. You can make your own dhamel leather if you want to save some gil, but of course that will take a longer time. As far as desynthing them, 8/10 times you will fail so i dont believe it is worth it. You get secure gil by selling to the NPC and using that to buy more supplies. Although, i did try desything alot at later levels, it was mostly because the materials are alot more difficult to obtain, but at your level its pretty easy to buy or make your own ram and sheep leather.
