You should have enough time for the bees to build up two brood boxes, and MAYBE store enough honey for the winter. Depending on how many pounds you need to make it through the winter.
I wouldn't expect too much more. I'm guessing that at the very best you might get - 2 brood boxes, 1 honey super, and weather permiting 50 to 75 pounds of honey. And at the lowest - 2 mostly finished brood boxes, with 20 or so pounds of honey (mostly on the corners of the brood frames).
Just my guess. :)
