I went to the tuff Shed site, but for some reason when I input the Zip Code for you it comes up with their St. Louis, MO store. That site only lists garages up to 24' x 30' like I stated. Very strange, but I'm glad that you found a bigger one listed. If you can get a break on the concrete work that will make a big difference no matter who builds your building. Perhaps your friends know of someone who will build your shop cheaper too.
