How to SHUFFLE rotating testimonials?

How to SHUFFLE rotating testimonials?

www.WEBCO-MN.com - scroll down to "What customers are saying"
to see an example. (Apologize in advance, I'm not a crazy coder. I know the simple stuff, and I know nothing about javascript)

I found a simple code that allows me to enter the text into DIV areas. 
I have a number of testimonials to add still, but the customers that go to our website will only see the first few every time, I'd like them to shuffle.

I'd also love it if there was a way to be able to hover over the text and make it pause?

This is the javascript I'm using to run it:

  1. (function($){
        $.fn.extend({ 
            //plugin name - rotaterator
            rotaterator: function(options) {
     
                var defaults = {
                    fadeSpeed: 600,
                    pauseSpeed: 100,
    child:null
                };
                 
                var options = $.extend(defaults, options);
             
                return this.each(function() {
                      var o =options;
                      var obj = $(this);                
                      var items = $(obj.children(), obj);
      items.each(function() {$(this).hide();})
      if(!o.child){var next = $(obj).children(':first');
      }else{var next = o.child;
      }
      $(next).fadeIn(o.fadeSpeed, function() {
    $(next).delay(o.pauseSpeed).fadeOut(o.fadeSpeed, function() {
    var next = $(this).next();
    if (next.length == 0){
    next = $(obj).children(':first');
    }
    $(obj).rotaterator({child : next, fadeSpeed : o.fadeSpeed, pauseSpeed : o.pauseSpeed});
    })
    });
                });
            }
        });
    })(jQuery);

     $(document).ready(function() {
            $('#rotate').rotaterator({fadeSpeed:1200, pauseSpeed:6000});
        }); 

    </script>
