Tips on creating a GMod DarkRP Server?

I would recommend you to go on the popular servers and just look at the addons they have and how things work such as what kind of ranks they have and where they place specific things such as the Inventory Bank and Meth Addict NPCs, things like that, also looking at the donation system and checking the different kinds of jobs they have to get some new ideas. Also a great way to make a server is to download the dedicated server and basically work on it and add new addons and stuff then once everything looks good and works perfectly you can go ahead and buy a server and just transfer all the files from your dedicated server onto your paid server. Hope this information helps you! :D
