@SeoDealer please don't take in a bad way what I'm about to say ( I previously made some good deal with you )
But.....
- 1K to invest per model ? It's already a bad idea unless you're her Boyfriend/ PIMP
I think BTC make you better profit on investement these days to be honest 
- Studio Owners with no money to get started with equipment should not be called Owners
- Profit Split = Models -> Owners -> Studio expense -> Yourself .......
- Contract not worth much after all... Your dealing with model with an Empty bank/ Broke model.
Not even worth it to sue them for 1K...... Last time I check my lawyers fee's was about $500+/ hours Locally
