Suggestions and what's not! What RP!!?

Hello people of facebunch!

I am creating an RP server at gmod and I am not sure what RP version to use.

I want it to be a serious RP, not darkrp, an I want it to be kind of realistic.
I am not sure where to download these gamemodes. (except darkrp, that’s easy to find.)

Whenever people want to get a job, I want them to either talk to someone, or use some kind of similar system to that.

Not sure how to describe it all haha - Please note, I am the best lua coder, or coder in general either.

Thank you for your time!

Not the place to ask for help, see Developer Discussion for lua stuff or general for server advice/chat
