Hi,
I would like to have a list of 5  to 10 companies that offer commercial
virtual mailbox addresses similar to (regus=hq).

The business mailing address rented from those companies should be in
San Francisco Bay Area and offer service well below the $95 a month
asked by regus.
The business mailing address should be looking like a prestigious address:

Example: California, Bay Area - Redwood Shores (Regus) 
303 Twin Dolphin Drive
6th Floor
Redwood City, California 94065
United States

For more information just ask for additional clarification, I will be
happy to help, take a look at www.hq.com to have an idea of what I'm
lookimg for.

Thanks
