Who the F*ck was building the Mass Production Evas in the Rebuild movies???

I just finished watching the Rebuilds for the first time and I can't stop thinking about the Eva army we see throughout 3.0+1.01, specifically the logistics NERV must have set up to make them. Even granting some kind of sophisticated autonomous factories and mines and whatnot, there must be a number of people working behind the scenes to make it all happen. Who's commanding/feeding the Ayanami series? Running supply chains? Designing fucked up evil weapons? I don't think Gendo and Fuyutsuki are that capable alone. NERV cultists? Desperate survivors? More Rei clones?
