I read REDDIT with one of the guys of Girlsdoporn; their productions costs for 2015 were over $300K. Broke it down like this, talent- over $10,000 a month. Travel- $5K a month. Productions costs, $5K a month ( hotels, equipment, etc) website, legal, etc.

He would not say if they turned a profit, which is very unlikely ( you can get a monthly membership for $15). But guess it's a team og guys scouring Instagrams, Facebook, modeling agencies, etc, to land the talent.
