I would suggest working out a deployment strategy that is portable, or at least prepare for more than one scenario.

If this is a one day event and you have a PR cost for it you can't afford to be in a situation where you can't deliver based on your choice of service provider.

Could probably use puppet or something and just get the appropriate keys. Get some sort of dynamic DNS set-up.

You could probably spend a couple/few hundred an hour for somebody with expert level experience to bang out some scripts for you, just to ensure it's been well configured and hopefully given some sort of stress test.

This sort of stuff is possible with today's available infrastructure. We really have a responsibility to use the tools the best way we can.
