Flat-coated Retriever Puppy Wanted

Hello, Currently we have a Golden Retriever of 12 years old and we have to admit he won't be with our family until eternity. So we're looking into the options of buying a flat coated retriever puppy in the near future. Please advice following: (1) Breeders points within Belgium? (2) What price can we expect to pay for a flat coated retriever puppy? (3) How to order a flat coated retriever puppy in Belgium? (4) How much time will it take between ordering and welcoming the puppy into the family? (5) Can we visit the puppy during the nest time? Awaiting your earliest reply. Fam.
