Hello,
I can help you with your Sonarr, Radarr Setup, I am also running a one my linux server since a long time with Sonarr/Radarr/Lidarr ( fully automated plex media server) I've a lot of experience in the media server setup stuff, It will take me few hours to set up sonarr. If you want to check my own setup feel free to ask.
Please contact me so we can discuss further.
