The most difficult item to get is the level 1 headpiece, which requires finishing the ARR allied beast tribes quest. It took me about a month, I'd say? Nhaza'a has a custom-colored version of the Raptorskin Shirt, I believe. For his PLD set, he can use a Bronze Spatha. For his shield, it's best to have the invisible shield which can be obtained from the Gold Saucer for 100k MGP.
