Hello Michael,
I am sorry you have felt that support has not been able to help you. I have responded to your latest ticket, in hopes that I may answer some of your questions there. I will also try and shed some light on the questions you have brought up here as well.
In regards to Plesk Control panel, it is in fact free for the ten domain package, meaning no install or monthly fee, and you can manage all your services from an easy to use panel. As far as installing your own control panel on a VPS, it is not advised, although technically possible. With a VPS system, you are limited to 512mb of memory, and you share processor time with the other users on the server, these limitation typically do not permit the use of other control panels as they load services specific to their panels, permitting them to manage your server. The Plesk Control Panel is different in the way that it is built to work with Virtuozzo which is the virtual environment software we use.
In short, although it is possible to install a Control Panel other then Plesk on a VPS, it is not recommended and would subject you to the possibility of your server becoming unresponsive or worse.
If you have further questions regarding this matter, please either reply to the ticket or PM me and I will be happy to assist you further.
Kind Regards,
Joshua Knapp
