Roleplay Game mode?

Hello,
We are a Roleplay community in alot of games and resantly came across all the multiplayer mods for gta and i know a little lua and c# and so on but im wondering if theres and good roleplay based gamemode out there that would be good to start on with the basics like

1.Car ownership
2.Money system
3.car dealers
4.shops
5.Jobs
6.Cops

We just need a base template and was wondering if there is one?

Here is the best I could find

I think you need MYSQL but
