I ordered my wedding and grooms cake from Hippy Chick Bakery. She's actually in NH but does deliveries all over the area. We had our reception in Cambridge and our cakes were delivered on time and intact. She's amazing and does really nice work. http://www.hippiechickbakery.com/
Edit: I posted the above before reading the fine print at the bottom of your post. I still stand by her and will say that her cakes are gorgeous and delicious/decadent, so you might still want to consider her as an option.
