i might be a minority say a 1 in 50 thats still 1 million people, you have to maximise everything in business, If i was employing someone i can see instantly with a land line where they are based and are not just some travelling new age hippies who fleece everyone when they arrive in town, a bit similat to " i am just laying some tarmac for the council and have got a bit left over , so i can lay your new drive cheep geezer " "just give us £500 and you will never see us again"
Roger just put your phone number nobody can beat you up down a phone line, If you are concerned just get an extra BT line just for business.
