Make a goal to acquire the following gathering accessories, either through the marketboard or the good graces of crafters. You can supply the hardsilver yourself; only 6 ingots are required for this set.

- HQ Dragonskin Choker
- HQ Dragonskin Ring x2
- HQ Dragonskin Wristbands
- HQ Hardsilver Earrings of Gathering

Wearing all of these will give you 597 GP with zero Materia melds. From there you can meld a single Gatherer's Grasp III materia, or avail yourself upon the Gold Saucer's cheap supplies of antelope stew.
