Yes, NJR Partnership does work from a SOHO. The routine is established and the discipline is in place to make a success of it. If you work from a SOHO advise potential clients about this. I don't understand why so many SOHO workers pretend they are large corporations.
One of the most extreme manifestations of this is a business I know (not a client) who has a trading room sound track as part of the telephone answering system. I'm not sure this "fools" anyone and is it a good thing to do.
