We were in a similar situation this past October and had only 1 week to get everything furnished and setup. We drove down in a truck with some stuff (electronics, mattresses, linens and other misc. items - e.g kitchen appliances) and arrived late on a Friday night. We then went out to Showcase Direct Saturday AM and picked out the big stuff - 2 BR's, living room, DR, and 3rd BR computer furniture. They delivered and set everything up 4 days later on Wednesday.
Various misc. pieces -- lamps, bar stools, TV stand, etc. - were purchased at Kirklands, CostCo and Best Buy.
