If you want a family pet that could also do SchH, those dogs are certainly out there, but the odds of finding a white one are slim to none, unfortunately. The white dogs make nice pets but haven't been selected for working ability for a very long time. They can do well in obedience, agility, that sort of thing.
I have seen photos of white GSDs in Europe doing bitework, so it's possible you might be able to import one, but it would be costly and you need to know the right people.
If you decide that you really want to do SchH and be successful at it, and you don't want to import a pup, you'll need to fall in love with sable, black and tan, bicolor or black... and find a breeder who trains and titles their dogs in SchH.
