Stairs: Organising sanding & staining

So we upgraded our stairs to cantilevered hardwood stairs and stainless steel balusters; but they come in a raw finish. We want them stained charcoal to match our front and rear doors - in fact, we want things to look pretty much like this picture below;


...with nice dark wood floors through all of downstairs, and dark stained stairs & handrail. Got in touch with a guy recommended to us from our earlier SS, and hopefully he'll get back to us with a quote. Ideally we want the stairs sanded and stained pretty quickly after handover, and before the carpets go in. Hopefully won't take too long - stairs will need sanding first, then a few coats of stain with drying time in-between each coat. Maybe a day's work?

Also the picture above is from the Nolan on display in Point Cook, which apparently has just been sold. Don't know if it's still open as a display home; we only visited it once. Just looking at the picture above, it's got huge entry (external) doors placed to the sitting room on the right - expensive! The bulkhead in the entry hallway is about $1000 option.
