In before someone posts a rude reply to this.
1) Most people don't check their server boards. FFXIAH has a nice self contained community, but for buying/selling I know people don't go to the forums to look for that
2) They DO go to the "wanted/bazaar" features on the site, if they have something to buy or sell. I suggest posted a "Wanted" list with these items for the price you're willing to pay and see if anyone bites.
Or if you're desperate you could try shouting in Whitegate. Sometimes you get lucky.
Good luck!
