If you wish to set up a mail forwarding address for privacy, many of our clients are using the virtual office services offered by Davinci Virtual Office.
A no-cost option (as in FREE) to set up a business phone number is Google Voice. Once created, the new number can be set to ring as many other phone numbers as you wish.
Electronic FAX services also provide a cost effective means to receive or send FAXes from your PC. We use MaxEmail for our companies.
