Help with my new Gmod Dedicated Server.

I just purchased a Gmod server and I am having TONS of problems setting it up. I am in need of some help. If someone wouldn’t mind helping me setup/install what I need on the server, I will give full access and admin to the server. You also may add what you would like to the server or test what you want. I am using DarkRP and need help with some things about DarkRP. I am new to this stuff and do not know how to do a lot of Gmod Server Stuff. If anyone could help me, please pm me or add me on steam and message me.
