I've recently thought this would make a great business model. You set up a service where you deploy open source tools like email, picture storage, etc to run on aws lambdas for people. All they would need to supply is a domain name (via oauth access to dns providers) and an aws account. For a single user, the app's costs would probably be under a dollar for a year. They pay you a one time setup fee, and a maintenance fee only if they want to receive updates. Configure nightly backups for them, etc. I'd definitely pay if this existed already.
