Ideal world, meet actual world.
It appears daunting, but once you get over the hump you can't imagine how you ever survived without it.
If you have a mythical quiet Friday afternoon install Vagrant and try and replicate your manual setup steps for a new server and share it with your development team.
Even just having the steps required to set up a development environment represented in re-usable versioned code is worthwhile.
Next time a new hire starts that afternoon repays itself when they have a fully working dev environment ready in less then an hour.
Going from that, to doing this stuff in production is a lot of work, but you get similar pay offs at every step as long as you're willing to invest a little time.
