Any private servers where we can practice the fight caves / Jad fight?

I'm looking for a private server where I can practice the fight caves / the final fight with Jad. I'm hoping this exists somewhere without needing to train up an account or anything. Let me know if you know of anything like this.

 

There's a few rsps who offer the inferno where you can start at a certain wave, I know Alora has inferno training tickets and you can purchase one for like 5M in-game which isn't much at all, and you can practice that way.
