If you want one of his family then I would suggest that you go back to his breeder for another puppy in about 18 months time.
One off stud use is not a good idea, and the type of breeder that would consider using your dog is unlikely to prodcue the sort of pups you would like. Producing quality pups requires a great deal of knowledge of the lines in the dogs and bitches lines as well as a good dose of luck.
You will need to get your boy Hip Scored (cost around £150) Heart tested (£?) and really he would need to be shown for owners of good bitches to see him for them to even consider using him.
Have you had him assessed by independant expersts to ascertain if he is of sufficient quality to be used for breeding, the first persons opion to be sought ought to be his breeder, but soem unbioased opinions would be needed in addition.
Also you would be morrally responsible for the life4long welfare of any of the pups he produced, and would you be able to help the bitches owner with rehoming a possibly difficult adolescent or adult dog?
