You're basically demonstrating why people don't want to deal with you - you don't want to be found. That's why people want real addresses. Even if they never have to find you.
I work from my home. My home address is listed as our business address. I have a toll free phone number that gets answered through the day (absolutely - I want customer calls). I don't have any problems. Actually the only problem I've had is a sales rep saw an article about me in a newspaper and decided to drop by unannounced, realized it was our house, and called instead.
Get a toll free number, forward it to your cell phone and answer it when it rings. List your home address as the business address, then make a note that is a shipping address only and there are no customer service facilities at that location.
Remember, people don't necessarily want to drop by. They just want to deal with a real business that's not anonymous. So pick which one you're going to be.
