.... and here more clips from this studio shooting

How much did you pay her?

200 Euro

I know a lingerie model who works for about $500 dollars an hour with a min of 3 hours and travel expenses must be reimbursed. Casual clothing models seem to charge $75 an hour, and I have been offered work up to $150 dollars an hour. If someone doesn't have a portfolio and lacks experience $50 dollars an hour seems to be the rate. However you could probably get away with $10 dollars an hour, because most women just like the idea of doing modeling work. lol!

300 EU a whole day (6 hours) and a nice dinner.

I'm not to the point of higher priced models like these above so my rule of thumb is $15-20 an hour for adults with a 3 hour minuim. $10.00 an hour for kids.
Then I won't shoot with another paid model until I recoop the money for the first shoot.
It seems to work for me.
This was one from last weekend, she was a girl I worked with and her 2 sons.
