As a frequent customer of these businesses I must concur. I am constantly switching from one print shop to another because of poor customer service, declining quality and staff untrained in the use of requisite software/hardware.
Make sure whoever you hire is courteous and knows how to use design software competently, knows basic hardware/software troubleshooting and can operate the machines. It is really frustrating to have to show the person you are paying to do a job how to carry out a task.
In a place where thought is abandoned, freedom can become a curse.
