Since you're in Windurst, I'd suggest the quest from Yoran-Oran where he collects interesting Mandragora related items.
Tear through mandragoras and throw nothing away. Keep the cotton and sell it in stacks of 12 on the AH. Keep the earth crystals and sell those as well. You can collect as many cornettes as you can hold, but once you have one piece of Yuhtunga Sulfer and one 4 leaft Mandy bud, run back to Windurst Walls and cash it all in. You can get 2000 or so gil a run from the quest part, and a stack of Saruta Cotton sells for a pretty penny on the AH.
