We come across this problem very often; Clients don’t want to publish their contact information on their small business website – with exception of e-mail / contact form that is.
Personally I never buy anything from websites without full address information and phone number and know many people that they have that same approach.
Businesses that operate from home often face that dilemma. Even that they publish their office hours, there are always people that will call at 2:00 AM. One way to get around that problem is to use Skype number and put it on automatic reply after business hours and activate it again in the morning. It is also very practical solution because you can forward it to two phones to ring simultaneously, which is great if you’re out and about. www.skype.com
