1. Get a PO Box. Its stupid cheap. Get the smallest one possible. 2. I have had the same cell for 15 years. About 10 years ago, I added a second cell. So I look like a drug dealer, but LOVE having the second cell, so I can turn the business OFF. But I get calls that start with "12 years ago, you helped my mom". I will never release this number. 3. I can mirror my phone number on my cell with the phone app. (I really don't get how this works. But the man is a telecom guy and he set it up for me.) I don't like the virtual office solution, because I know too many that have gone out of business or changed addresses. Which leaves you having to update business cards, mailers, etc.
