Currently the item Truegold is selling for 1.4k on my realm and can only be made by Alchemists. A standard fee for the Xmute is charged so there's some money there but if you are Xmute specced you can sometimes proc for 2-5 Truegold instead of just 1. If you simply trade the mats for the Xmute for the Truegold itself you can charge a fee and then do the Xmute yourself later on and potentually proc. You can repeat this endlessly [well once per day] and sell any additional Truegold on the AH. so far this has made me 1.4k in fees at 200g charge and 2.8k in procs over 7 days, giving my an average of 4.2k per week or 600g per day.
