Hello. I've had clients ask me to make one that works and isn't buggy, out of trust in my work. Generally if it exists I don't do it, the reason is that they want it to meet their needs and be customizable:

+ UI editable
+ Restriction system per Playermodel
+ Be able to customize access and restrictions by jobs, ranks.
+With the ability to reserve playermodels for ranks, classes, jobs. And that includes saving with : Gmod Character Creator System
+ Content for VIPs
+ Support

If a client asks me I do it. And I provide support for adaptations and updates. I get so many requests that it's a job.

124 updates is the number of updates just for 2022. Which are mostly customer requests. I respond to needs on demand. So I am a worker responding to requirements. If there's already a free one that meets your needs that's fine, for you.

Why does this cost money, there is already a free version
