Please do read the threads Summerrain linked - if only to spare the forum another of my (experience-driven) soap box speeches.
You have not mentioned if you are a member of an FCI club, and of the Swiss Border Collie Club. As has been discussed in the other threads, only breed club members should breed; only breed club members are allowed to breed under the egis of the SKG Border Collie Club (i.e, the organization issuing the pedigree) - which only recognize a member dog who has gone through the Ankörung process of judging whether the dog is - or is not- fit to breed. Ankörung requires several health tests to be done, as well as temperament tests and conformation judgment.
Here are the breeding regulations of the Swiss Border Collie Club:

Bear in mind that if you are not a member, if your dog has not passed the Ankörung, the puppies produced are not eligible for an SKG/BCCS pedigree, regardless of the status of the sire and dam. You may not sell such puppies as 'pedigree'.
As you contemplate this very serious step, please read through the Border Collie Club website - especially the news articles dealing with epilepsy and cobalbaminmangel in the breed.
** There is only one proper place to find a suitable stud dog - from the list of properly Angekört studs kept by the Züchtwart of the BCCS. **
In addition to the breed club rules, you will also need to comply with the Animal Welfare Law (TschV):

As you can tell from my posts in the linked threads, rescue is my thing. I got involved in rescue after my experience adopting a rough collie who had been taken from an abusive situation. This collie came from a very well known breeder in Australia, his pedigree was littered with national and international champions. He was sold as a puppy to someone in Hong Kong, probably as a trophy toy. Well, somehow that champion pedigreed puppy ended up starved, beaten, a mental and physical wreck, abandoned tied to a balcony during a typhoon...
I've written extensively about my collies and shelties who suffered from various genetic disorders; all had been produced by breeders who either lacked the necessary knowledge of genetics, or who simply didn't care. My guys should not have been born, given their genetic make-up. They suffered needlessly due to inherited conditions, one died far too young.
And then there is my youngest sheltie, the reason I have gone prematurely gray.

She came from the kind of situation Gata is refering to. The breeder could not sell her, no one wanted her, she was 'surplus to requirements' - and so left to run wild about the breeder's farm, no training or socialization whatsoever for her first 11 months. Overcoming that lack of early socialization has made for an ... interesting ... 5 years.
Which is why I harp on about the moral and ethical responsibilities of a breeder. Ensuring the genetic health, ensuring proper socialization and training, finding the right home for the pups, and standing by all the dogs you produce for their lifetimes should the need arise - these are heavy responsibilities, not to be entered into lightly.

I spend my life with dogs who were let down by the folks who bred them... which is why I respect ethical, responsible breeders. These folks are working on the same problem I am by addressing the problem at the source, by ensuring that their dogs don't end up in rescue. If you are going to breed, please do it right, be one of the 'good guys'. Join the BCCS, have your dog judged by experts. Find a BCCS member to mentor you, to help you plan a breeding and early socialization program.
Wishing you and your dog all the best.
