You seem to be on the right track.  I'd use, while debugging, 
PIP_CONFIG_FILE to make sure you're really getting your file picked up.

proxy settings have to include a scheme, since you (understandably) 
obscured yours, we can't see if you're actually doing that.

I used to have this problem early on at my next-to-last corporate 
setting, sometimes you just need some help if they're blocking things at 
IT. Fortunately, haven't had to deal with that scenario for many many 
years now so don't have anything further useful to add.  I know the 
question comes up periodically, you're certainly not alone - maybe Stack 
Overflow has some suggestions?
