If you have left organising a puppy until 2 weeks before the date you want it, I doubt many reputable breeders will sell you one I'm afraid. A puppy (and, therefore a dog) is a huge, lifetime responsibility, not to be entered into lightly.
Most people who want a puppy will plan ahead and choose a breeder carefully. Maybe you should think about a puppy for next years Birthday? You could then meet some breeders (of YELLOW labs ) and get to know them and their stock before choosing a puppy :)
