I am preparing to mail out my introduction letters.  I have compiled lists of both Preschools/Daycares and Assisted Living Facilities.  If I mailed out letters to everyone, it would total

almost (80).  I do not want to be inundated with so much business that it over whelms me, plus it would be almost impossible to follow-up that many. Thanks for your help.

How many introductory letters did you initially mail out?
