I would suggest the German Shepard over the Staffordshire Bull, for its temperament.
Pedigree animals have a commercial value, so I have not seen many in shelters. I hope you will still get a shelter dog even if you can't find the exact breed.
Below are some UK directories which list shelters by region.
UK Animal Rescuers
Dog Rescue Pagesh
Dog's Trust
Remember that if you keep the dog outside, it will have to remain in the vicinity of its own waste while waiting for urine to dry and poo to be picked up. You should toilet-train your dog to use a litter pad in the backyard, and you can consider a smaller breed which are easier to clean up after.
Little Dog Rescue
Shelter staff can give you advice for the specific dog you finally choose. Keep in touch with them, and keep us updated when you get your new family member.
