I apologize – I'm on mobile, so I can't really look carefully right now, but if you don't have time to run the site, perhaps you could convert it to something with lower maintenance, like YouTube channel?
I do see value in hosting outside of Vimeo/Youtube as the likelihood of having content DMCA'ed is a looming threat.
Right now I host this on a simple desktop computer running CentOS (an AMD Athlon X2 with 32gb of RAM, Mirrored 1TB hd)
I tried hosting it on a VPS and well, performance was so bad.
