Virtual Office Manhattan Best Virtual Office Software?

Best virtual office software? - virtual office manhattan

A friend of mine runs a small web design company in Delhi. His design team - all regular employees - in different cities of India.

Now my friend wants to create a virtual desktop via a Web service for collaboration, project management, etc., adequate storage space with a little file. Something that can use a Web browser to be accessed.

I wonder what is the best, reliable, stable, easy to use, in general, the Virtual Office service in the network. It may be free or something cheap. Your suggestions will be greatly appreciated!
