Any average bike shop should be able to build a wheel from a hub, but you'll certainly also need the controller bits that allow you to actually switch the gear. Some OEM kits don't have those parts. You should probably also ask your favorite bike shop if they feel comfortable doing maintenance work on this piece (or ask yourself if you do).

I'd keep in mind that the rohloff speed hub is an amazing piece of technology, so it comes with a hefty price sticker. I'd question it's really worth it for the average bicycle person when a shimano alfine 11 gear hub costs barely a quarter.
