I am willing to sell via TerrabitHost fully managed Plex Media Servers with the exact same setup that my server uses for £19.99 per month!
My server specs are:
80GB System Storage
Google Drive (GSuite) for film storage (advertised as 1TB however there is no hard limit)
Accessible via custom domain / subdomain
Personal Google Drive API App
I have managed 5 consecutive transcoded streams with no issues, i'm sure it will cope with more.
The streaming from Google Drive is managed with rClone with a setup which chunks the data as to not hit the API limits.
Fully remote... and accessible anywhere you have a internet connection.
Please feel free to contact me if you are interested in one.
