Effective marketing while working

[Walt Payne]

I am just researching the various aspects of direct mail. I worked for a direct response TV advertising agency so a lot of the basics are the same. My biggest concern is dealing with calls while I am at work. How is that effectively handled, especially when starting out and potentially getting a lot of calls from tire kickers? How do you keep the costs under control, do good screening, and not lose valid leads, all at the same time? Or should I wait until I can handle the calls myself?
