Cutting corners in any breed is risky business...but cutting corners in GSDs is playing with fire.
Depending on what lines of GSD you're talking about, the breed is in serious trouble. The LAST THING ON EARTH it needs is someone who's going to half-a$$ it as a way to make a few extra bucks. This is exactly what got GSDs into trouble in the first place. The only people that should be getting into breeding these wonderful animals are those that are willing to throw their heart, soul and paycheck (with no thought of return!!!) into it.
GSDs already have a bad rap with a lot of the general public- the last thing you want to do is PROVE to these people that their assumptions are right, by breeding animals that you don't have time for. Unsocialized dogs are a nightmare, unsocialized GSDs are more than that: they are risks for lawsuits just waiting to happen, or worse. These are big, powerful animals that can do alot of damage- so it is IMPERATIVE that pups are born from lines with rock-solid temperaments, and then socialized WELL.
This means HOURS UPON HOURS of work for EACH puppy. (And remember- time is money).
And the parents hips MUST MUST MUST be tested. This is NOT an option. Should you decide hip testing is too expensive- you effectively decide as well that you are a backyard breeder.
And you WON'T make money off of this. ESPECIALLY in this breed. Unless you show in conformation or work your dogs (in Schutzhund or herding etc.) you won't be taken seriously, and you shouldn't be. With so many people out there doing it right- why bother getting a dog from someone who cares only to do the bare minimum? You certainly won't get access to good breeding stock if you forgo working your dogs. So it's a necessity.
And campaigning GSDs is EXPENSIVE. It is well-known that this is a "handler breed" in AKC circles, which basically means that you will be more likely to win the lottery than you will be likely to finish your dog's championship owner-handled. (Unless that dog is REALLY spectacular). Your best bet is a pro handler...and they don't come cheap.
If you go the Schutzhund route we're STILL talking big bucks (and this is due to the HUGE amount of time you will spend training an animal in this sport). It's not really the kind of thing you "dabble" in. It IS the kind of thing that consumes your weekends, you weeknights, and eventually your life. But the people who do it LOVE that it consumes their lives. They could care less that they aren't making money- they love the sport, and they love their dogs.
If I remember correctly, you're the one who only has a few hours a day to spend with a single dog, right? In the most gentle way possible, can I suggest that breeding would be an absolute NIGHTMARE for you?
Breeding dogs IS a job....but it's one you DON'T get paid for. If you don't have HOURS AND HOURS of time to devote to tiny, helpless lives...it is NOT for you. Not only will the dam and puppies suffer, the BREED will.
