I'm not sure how many people know that Sulfuron Ingots can actually be turned in to a NPC inside of BRD for an epic BS pattern that sells pretty well.
To obtain the recipe, you do not need any reputation, you just need to find a way into BRD. The Plans are, [Plans: Sulfuron Hammer].
The NPC is inside of BRD and is named Lokhtos Darkbargainer. He is the Quartermaster for the Thorium Brotherhood.
What I do is just add the Ingots to my snatch list and buy them at or under 400g ea. I turn the Ingots in for the Plans and then list them at 2,000g+. It's an easy and reliable flip.
The only real downside to this is that you can't flood the market with the plans, as you're only targeting Blacksmiths and in my opinion they are few and far, compared to other professions. Also if someone else is doing this the market can become flooded even with 2 Plans up, it will just become an undercutting war which results in loss of profit.
I managed to flip another Swift Spectral Tiger Today, well not yet but I have a buyer coming with 16 Choppers. I bought the Tiger at 60k and it's being sold for about 220k. I've made roughly 250k in the past two days. I will also hit my first gold cap by doing these 2 flips :)
