Any artist who pays the bills using money derived from their artwork is going to find your offer distasteful. Even if the project seems to be an intriguing endeavor, the logistics make it extremely difficult.
Word to the wise: if you are offering $100, which is way better than offering nothing or offering 'exposure', but still isn't much more than material cost, your brief should be: "its a punk show, do whatever the fuck you want to do for $100." You would probably end up with something much better than zombies eating snowboarders, and you'd be happy with it.
But again, credit where due: offering $100 is better than offering "exposure".
