It depends on how she enters the industry. The vast majority of women enter via the “casting couch” or amateur “professional” route. If she has the right agent, she’ll get the same rate across the “usual” companies. She might get the most from the first shoot (maybe by $100-200) for the “privilege” of shooting her first video.
The companies are very familiar with each other and they work with the agent. So if they find out they weren’t the first, the companies might not work with the agent again.
I had mold in my CamelBak straw. I had the hardest time replacing it.
