If you do it on a sizeable scale be prepared to never take another vacation.

No, not on any scale. Just a couple of litters a year.
This is where I will be a little nasty. Bitches generally have 2 heat cycles a year. Unless you plan on having two females alternating litters, breeding one female every cycle is nothing short of backyard breeding and pretty darn close to a puppy mill. And it doesn’t give you any idea of how the pups turn out either.
Your whole ‘creating life’ angle, quite frankly, is scary.
