Does anyone know if there is any company providing commercial support for small enterprises using Kubuntu / Plasma DE?

The Kubuntu website points towards an initiative with a company called Emerge Open that appears to have been launched in 2013 ( but emails and phone calls unanswered lead me to believe that this is not longer working. Ubuntu is Gnome-only (dropped support for Kubuntu/Plasma) and has a 10 user minimum limit. Red Hat doesn't seem to have a desktop package any more only workstation (and besides RHEL is gnome). SUSE has no minimums but only supports SLED in Gnome.

Not sure where to turn. Any advice much appreciated.
