Never Bothered, Anyway

All recipes are sold by [npc=16365] after completing Putting Wilhelm Out of Business

If you do not wish to craft these yourself, all items can be crafted by other players through crafting orders since all items are "bind on pickup" and therefore cannot be traded or auctioned.

Here's a table showing which profession is needed to craft each item and the total mats needed:
