So, check the other tab in Mor Dhona, see what's available there. You may be able to buy stuff there that you can sell on the marketboard for profit. Failing that, you can buy the ironworks gear, hand it in for grand company seals, and then buy Moonstones with the GC seals, to sell for a nice tasty profit. It'll all depend on your server's economy, what sells, what doesn't, what brings in nice profit margins, etc.
