In follow up, I was going to send a private message (PM) but you don't have them enabled for your account. So I'll post it here, since none of it is actually private.
As an example of commercial, end-user support services ....
One of the services firms listed on the Project's
Commercial Support page is M:Tier Ltd. They are particularly active in support of the OpenBSD community at large, and offer a number of free services such as binary packaging for OpenBSD-stable users.
I mention them because their commercial services include ready-to-use Gnome workstation enviornments, something you expressed interest in. And regarding Gnome, their staff includes Antoine Jacoutot (ajacoutot@), who leads the OpenBSD Gnome porting team among his many other accomplishments for the Project.
I don't know if they would be interested in supporting individual customers rather than their usual corporate fleets -- but you could certainly ask, if interested.
