Lisa, since you probably do not have much freezer space available, this may not work for you...
but when I was selling soups at my Farmer's Markets, I used to take clean empty 2-liter soda bottles and fill them with water, and freeze them. When I would get done with a batch of soup and needed to cool it off quickly, I would submerge one or two of these frozen soda bottles in the soup, stirring it around occasionally, until the soup was quite cool, and then refrigerate it. It worked really well for me. Those same frozen liter bottles are also great to use in a cooler instead of ice. Layer some newspaper on top of the bottles to keep the moisture away from the food.
I would love to take credit for this idea, but it belongs to a vendor I used to work with.
