I have had a very difficult time with stage fright; it undermines your well-being and peace of mind, and it can also threaten your livelihood.
I think when you're looking for people to interview, you want to make it fair and honest. You're not just bringing people on so you can beat them up or, you know, make fools out of them or something.
Earlier, I used to charge territories instead of my fees as an actor, but I realised it was better to keep the two apart. Now, I take my fees in cash, for acting, and keep the distribution thing separate.
