Purchasing High Quality Prison Setup ($x,xxx Budget)

[GameyAI]

Hi there, I've got a 4 figure budget. Looking to purchase a very high quality, well monetized & optimized OP Prison Setup.
Must be able to handle 150+ players on an instance, 1.20.6 preferred.

Don't want it incredibly overpowered, want something more balanced, similar to MineJunkie. Must be well monetized.
