I know there has been loads of guides like this before, but this is my version that's simple and there is hardly no work needed.
1st. Professions, you will need mining, enchanting and jewelcrafting. All 600
2nd. (If you want to make max profit you will need HonorBuddy.) Farm ghost iron ore and trillium ore in VotFw.
3rd. send to your jewelcrafter prospect all the ore.(use a bot for this or it will take a long time.)
4th. keep all your blue un-cut jems and send them to banker(trust me turning them in to jems is to much hassle.)
5th. Make ornate bands and shadowfire necklaces (as much as possible.)
6th. Disenchant them all with your enchanter.
7th. Convert all your Spirit dust in to Mysterious Essence.
8th. Send to Banker
9th. Use Ah bot and auction all on the auction house
10th. Wake up with 10k in your pocket
