@jesta We hired @someguy123 to setup and manage viva.witness and he's doing a great job at a very reasonable rate. You might consider reaching out to him while you're away anyways and see if he can help you.
I mention this because I've always been extremely pleased with his work and he's extremely trustworthy. Hope it's helpful!
I'd prefer to keep running them myself, it's the best way to keep on top of changes and making sure I have a deep understanding of how things work :)
