Blackwater has training classes for civies though. My buddy ,who is a civie, took a few classes. They go by a different name now though.
Honestly MVT is at the top of my list for places I want to train.
Max Velocity Tactical offers civies any type of training they want from CCW to Active shooter training to carbine courses to CQC to small team tactics and combat conditioning.
Not very many guys are this open to training civies in actual tactical stuff. Heres a little on the head instructor that I copied off a blog:
" Max Alexander is a tactical trainer and author. He is a lifelong professional soldier with extensive military experience. He served with British Special Operations Forces, both enlisted and as a commissioned officer; a graduate of the Royal Military Academy Sandhurst. Max served on numerous operational deployments, and also served as a recruit instructor. Max spent five years serving as a paramilitary contractor in both Iraq and Afghanistan. This included working on contract for the U.S. Government in Iraq, a year of which was based out of Fallujah, and also two years working for the British Government in Helmand Province, Afghanistan. "
