My gut says that you need to wait until you find what you are looking for because, I am afraid that you will never be happy with this puppy. You mention that you have now been matched with a puppythat is the opposite of what you wanted. To me, this sounds like a recipe for disaster and I am afraid that the puppy will be the big loser in the end.
