I've spoke with few VA who could not afford to purchase a desk, chair or any office furnitures for their business establishment.

There is a great program, called Freecyle. I am member of this group in my area and I've seen many people offering their unwanted office furnitures for free. I've also seen people posting on freecyle looking for desk and was sucessful locating one.

Also...

If you wish to rid clutters or furnitures in your home to make more room for your office but don't have the time to take them to Goodwill or set up garage sales - you can turn to Freecyle and post items you don't want. Any interested party would come and take them off your hands.

You can check freecyle in your area and sign up for free.
