Lately i have seen alot of different money making strategies, and to be honest i dont really like the "go grind 1 zillion mobs and hope for a epix" or "level a rogue – mc equip him, and solo some boss"
This is the method ive been using to make cash! And alot and fast. Since i play on a server with 15 MC guilds, and 10′ish BWL / NAX guilds, i have been profiting alot of being one of the only makers of the infamous "Dark Iron" items.
For a list of items:

What i do, is i have made both a post on our un-official forum, and our official forum – offering my services, and since alot of people know who i am… they come to me when they need DI items.
The whole great thing, is i have one day each week, where i go to BRD and solo my way to the black anvil (I use reckless 
) and make allmost 20 items (depends ofc and **** )
Each item i charge 75g just to craft, since the other guy got enough cash on his hands, and he only crafts for his guild.
Conclution:
This can and will be very profitable, and it is.. atleast to me. Another thing is that to some people grinding TB rep to get theese sweets is in itself alot of hard work, but then again. Very profitable!
This is a guide ment for the people able to craft theese items, and to thoose who dont see the endless possibilities. The best thing is that there is on each realm, alot of new guilds forming, needing hunter/pally/warrior FR items, and for myself i got 303 FR (not even tank)… I sometimes make 25-30 items in a week, and sometimes i dont make anything in 1-2 months.
Remember: This is a guide for thoose who dont see the profit in helping/crafting Dark Iron items for other guilds/people
