You just need to talk your account rep (or sales if you don't have one). You will definitely not pay this price. I work for New Relic, so if you need help, let me know.
I hear you. It's just a matter of simplicity. We can't have every single environment configuration on the site. So, we have a few list prices with links to contact us if your model doesn't fit. I hope that helps. If you have other questions, let me know.
