Opus Virtual Offices is by far the most cost effective compared to other virtual offices. I set up my account via the Internet and received a call back within 48 hours to confirm my account activation. The live receptionist give our virtual office a physical feeling. Having the convenience of the Voice Mail and fax sent via email is extremely convenient for a traveling business person like myself. Not even a week of having the service and it’s everything advertised and I wanted in a virtual office.
