I'm on the unicorn server for any other BSTs who would like to do this BCNM. I've made anywhere around 200-600k average. With 6 BSTs this is as easy as you'd want it to be for fast money.
I've seen subs like: WHM,BRD,RDM,and NIN.
Any of those are awesome. If you sub NIN or RDM, pls make sure you have good CHR gear. Nothing hurts your chances like mischarm.
