What you would need, besides someone with the spare time to set this up, is an evil organization patterned after the ones that actually function well in the real world now, i.e. organized crime. Instead of being dedicated to specific evil deities and some sort of, "kill them all and take their stuff" only creed an actual semi-business model would add coherence to the company. You could actually set up the charter and potentially ally yourself with other evil or neutral groups to form evil nations that are basically after securing the bottom line. Especially since you could hire out as mercs to neutral or even desperate good nations when they come under siege. And hopefully, everyone will be coming under siege at some point :).
As an example of a command structure based off of La Cosa Nostra you could have:
Don--the main man, the one who runs the show.
Underboss--2nd in command.
Consigliere--a counselor, frequently has some authority, but primarily exists to offer advice and to settle disputes.
Capo--a captain, a leader in the company.
Soldier/button-man--a member of the company, one of the many foot soldiers who hear and obey.
And other organizations could pattern their companies after their yakuza, Russian families, Jamaican posses, outlaw motorcycle gangs, etc. The point is, evil can be organized and profitable IF people let go of the mentality that being evil means that you can do whatever you want. Instead, you work with the company to maximize the profits of the company.
