Alright I couldn't find this here but I ran into a website Always Current Crafting Guides for Guild Wars 2 This website was awesome and let me complete tradeskills in WAY less time than fumbling around with set guides. From what I understand it somehow checks the prices of the auctions and mathematically calculates the most cost efficient or fastest way to complete a tradeskill. For example I used the Jewelcrafting fast guide and after I purchased the mats I went from 1 to 400 in under 10 minutes. It goes step by step and it will even show you the shopping list per tier if you do not have big enough bags to hold all of the materials at once.
EDIT: The title may be a bit misleading after reading it again it sounds like I'm saying it does the crafting automatically.
