Just an idea, why not meet a breeder with a litter, ask him/her if you can come back and choose a puppy, then film the puppies all together and give your husband the tape to watch, that way he gets to pick his own pup, which is half the excitement of getting a puppy, plus the puppy can come home to the place it is to live, and settle in straight away.
Another thing to think about is the fact the puppy at this stage may not have it's vacinations and you might therefore be putting it at risk, taking it into the school. Also the puppy might find it stressful going from the breeder, kept somewhere out of sight then taken to the school and finally to your home, which would not be the best start for the puppy. Another point you might like to consider is that by filming the litter you will have a nice keepsake of your puppy from the time she was in the nest with her mum and litter mates.
As to breeders try contacting the labrador clubs and KC. Have you also looked on here at the breeders listed here? Do remember to ask the breeder to show you the eye test certificates for the sire and dam of the pups and the hip and elbow scores. Your vet should be able to tell you what the average score is for hips and elbows in labs.
