Personally, Jewel crafting and Enchanting makes me more gold than other professions(AS FAR AS WOD CRAFTING GOES)
I can't get enough for the following and the reasons why!
X-mute master Alchemy- Daily craft on Living Steel---OR----Living Elementals for Volatile Waters
Blacksmithing- Daily craft on the Lightning Steel Ingots(Craft the 502 reborn weapons for Xmog) 20,000-35,000 every 30 days
--By product can do WoD daily craft and WorkOrder/Rush Work Orders and craft the WoD Upgrades/Pet
Engineer- Daily craft on the Jard's Peculiar Engergy Source(Craft the 2 pets OR the Sky Golem mount) 20,000-27,500 every 30 days
--By product can do WoD daily craft and WorkOrders/Rush Work Orders and craft the WoD Upgrades/Toys/Pets/Gun enchants
But to do the whole Blacksmithing and Engineering you want a miner to smelt the Ghost Iron and Trillium Ore, can always buy these in Ore form rather than Bar form for a lot cheaper.
If your purely after quick easy gold, go with Enchanting and Jewelcrafting. Can be 100% self sufficient with running Garrisons with double garrison resource trait on followers and when the ore/dust is only 4GR per item, buy stacks of it.
I currently run 16 level 100, with level 3 garrison(buildings upgraded) and I have 100% self sufficient(never have to buy anything out of pocket) for the daily crafts and work orders and rush work orders.
Hope this was helpful for ya!

**Edit** I just crafted 3 more reborn weapons today, sold them instantly for 35,000g each. Not even on AH, so 100% of the price
