My advice again, start with a female.
Forget the male. Easier, cheaper, and in most cases better breeding to select the ideal match from the many studs available, once you have a better idea of what sort of dog will be a good match for her, than to get a male yourself. And again, there is no way for you to ensure that any male or female you were to purchase would be good mates for each other, no matter how great they may be themselves.
Take that female and work her, live with her, get to know her. Let others with more experience get to know her a bit and give their opinion. As you work her, keep your eyes open to other dogs you encounter as this will help you learn more about what traits you value and don't like and what makes a good working dog. All of this is much better learned first hand, through experience.
During this time study pedigrees and bloodlines, and find a mentor in breeding who can help you learn about the ins and outs of breeding. As you work her, you will glean an understanding of how she measures up and be able to determine if she is worthy of breeding and represents the sort of dog you want to breed. You'll also become familiar with her strengths and weaknesses, then when she is ready and you are ready, find the best stud you can, one with a complimentary pedigree and characteristics, and who will help enhance her strengths and compensate for her weaknesses, and likewise she will do the same.
Do those things, and you'll be well on your way to becoming a great breeder.
