Furniture moving through windows?

Wasn't really sure how to title this, but basically we ordered a washer/dryer combo and we got it up three flights of stairs but at the top, where our condo is, we couldn't get it up the spiral staircase.

Do we have any options here? Does anyone know a company that can help us with this? We were thinking of getting a company that parks on the street and lifts it through the front window, but one estimate we got was semi pricey.
