500 Calls per day? You are going to be burning thru people like there is no tomorrow. 1/2 that number of calls is "less than reasonable". By the time you figure in ring time, introduction, and possible conversation...or even simple "not interested's", it isnt feasible to call 500 businesses a day per person. It might be different calling residences because there are no answers, disconnects, and voicemail but the majority of Businesses will actually answer their phones. Then there will be additional time off of the phone working deals.
