I explain further; below is the line of questioning: Do you have a blank (my product): 75 plus% will say yes and you'll say thanks and hang up.? ? There's one qualifier - if they say yes, but it's broke, it doesn't work, etc.? I want that noted.? ? If they say no -? I want that noted.? I additionally, want? it noted if they? say no, but there's on next door, there's one across the street, etc.? I? don't need to know? where the other is, I just want to note that they had other options,? as opposed to a? plain no.? ? I have an additional? 5000 or so businesses, but I? feel a trial? may be best.? ? ? ? ## Deliverables This will be done over the phone if that wasn't clear.?
