hello and welcome to the forum, try the kennel club they have a list of breeders.
I would always make sure you see mother and litter mates, and if you are ever suspicious about a breeder do not buy from them. If you want to go away and think about it and they pressure you into buying there and then there is usually something up, all reputable breeders will want to make sure you are happy with your decision, its best for both you and puppy. Hope this helps, if you want more info just ask, there are many people on here with lots of good information and advice. Hope you find the right pup for your family
