I need to purchase a lot of ten desks for very little.  Where can I
find a place that will give me a multiple discount in Los Angeles,
Orange, and San Diego Counties.

If the desks don't have to be new, maybe look for bankruptcy auction
ads or other ads for used office equipment.

I would contact local demolition contractors that perform interior
demolition work also known as gut-outs, strip outs.  Our company,
Dallas Contracting Co., Inc. ( www.dallascontracting.com) specializes
in building demolition as well as interior demolition, strip-outs and
gut-outs.  During this work we typically run across numerous desks and
other furtiture.  Depending on condition we typically truy to sell or
give them away so we dont have to dispose.  Try your local phone book
or type in demolition contractor is the search engines
