I wouldn't suggest a Border Collie, Springer or Beagle for a first time dog owner tbh. I breed Golden Retrievers and I'd even be extremely reluctant to home on of them with a family with a one year old. I would consider it, but they'd really have to prove to me they had done their research and knew what to expect and how hard it might get.
I think you need to decide what sort of dog you want and what you want from a dog, how much time you have to put into it and how much walking you are able to give, whether the dog will have to be able to have the odd day without walks if the DC are ill or something and whether the breed in general can cope with this without being miserable and wrecking the place! Then, once you have done all that and narrowed it down to a few breeds, get in touch with the breed clubs and find a few breeders to go and talk to about the breed in general and what having a dog of that breed will mean to your family.
I would honestly steer clear of any breeder advertising pups that are 'ready to go' or that advertises on websites such as Epupz or the local paper. You may well find a good breeder advertising in those places, but unless you really know what you're looking for it can be a minefield, so I really wouldn't recommend it.
Bearing in mind whatever dog you get is likely to be with you for 14 years or more, and that you are first time dog owners, please be prepared to pay a decent price for your pup, to find a good breeder who will be honest with you, that has enough experience of the breed to be able to give you good advice and who will be available for 'after sales' advice should you need it. To do this you will need to go via the breed club for your chosen breed and almosty certainly be prepared to go on a waiting list for a puppy.
The breed club websites are a good place to get general info on dog breeds, but do remember this is just a guide, all dogs are different, even within the same breed.
