It appears he only communicates with certain people on the phone, phone messages or emails.  Does he also keep the door to his shop locked and only let certain people in to drop off or pick work for him to do?    You have to communicate with prospective and past customers to stay busy no matter how busy you are at the present time. 


Does his Paypal account still accepts prepayments for parts and services?


I have found that the one call you almost did not return could have been a missed opportunity of a life time or a very good customer.  No communication.....no new work.  No new work ........your business is just another failed business for the record books.

I was very busy and thought that the guys that left a phone message was just another window shopper.  I almost did not return the call.  We built enough product in four years and the profit from those products paid for the land and the 5000 square foot building where we still conduct our business. Commercial real estate is not cheap in big cities.
