Moving Job: Murphy Bed Delivery and Setup

I need two movers to move my Murphy bed when it arrives. It will be delivered in a window from 11 AM to 3 PM and is in a crate, which may need to be taken apart to remove the items for carrying up the stairs. There is one flight of stairs outside of the building, followed by three floors of stairs (two short flights per floor). The package weighs 523 lbs but can be taken apart to make it lighter.
