If you are stuck with Blacksmithing and Enchanting, you probably don’t have much luck making gold, and you should go level two gathering professions. 
That being said, I know of one guy who makes a little with the following strategy.
Buy:
1x [Eternal Earth] 5-8g
1x [Eternal Water] 4-6g
1x [Eternal Shadow] 4-6g
4x [Saronite Bar] 1.5-2g (total 6-8g)
1x [Eternal Water] 4-6g
1x [Eternal Shadow] 4-6g
4x [Saronite Bar] 1.5-2g (total 6-8g)
you buy mats for 19-28g and the buckle sells for a minimum of 50g going up to 100g on weekends.
Thats up to 81g (-auction fee) profit per buckle.
Here´s another one, buy:
disenchanting this gets you 1x [Dream Shard]
you invest like 11.5-15g and the [Dream Shard] goes for like 19-29g on my server
So, typically Blacksmithing and Enchanting are horrible for gold-making, but this tip might at least help you make a little with it.
