Cupcake/Sweet Treat Delivery in Triangle Area?
Favorite area bakeries are Sugarland in Chapel Hill (http://sugarlandchapelhill.com/), Sweet Memories in Apex (http://sweetmemoriesbakery.com/), and Edible Art Bakery in Raleigh (http://www.edibleartbakery.com/). Edible Art does list delivery for special occasion cakes on their site, but you'll need to call the other two to see if they also offer this service.
You may want to get bakery recommendations and then find a concierge service to pick/up and deliver.
There may be one of those companies that deliver meals from various restaurants in CH/Durham - perhaps they could be persuaded to do this.
Sorry I don't have more specific information to help you.
