We are currently a custom webhosting provider that has been around since the dawn of the internet (93-94).

We currenty just expaned our space buy about 1000 sq feet.
If we turned it into colo space or even dedicated server space, what kind of services would customers look for in something like that?

I figure we'll need a larger generator, and cooling.

We currently have TimeWarner and a local Tier2 provider for bandwith.
