I think it's a great idea. It's not much of a secret, but I have been halfway starting to set up a website to offer monero nodes to be set up. Life is very very effective at getting in the way at the moment, so not really coming near finishing that. The thought was it should be a community service, and as such people would only pay for the vps/hosting. The site wouldn't have any revenue. Alas, it is not on the top of my to do list at the moment.
50$ a year is not a lot for a whole node. Can't get much VPS in town for that.
