Hi! I'm an active player of CS:GO and I've got a lot of experience with game servers, including CS:GO (bhop servers, retake servers, 1v1 servers, knife servers, casual/competitive servers). I've setup quite a few servers before.
I also have a lot of experience with handling and setting up linux servers - I've got a couple of VPSs myself.
I've definitely got enough experience to quickly complete your project to your liking, including installation of sourcemod and other plugins. It will be completed to a professional standard.
You can also trust that I'll be available in the future if the server needs any updates or fixes!
I'm looking forward to setting it up!
