I would say £2-300 to cover health tests.
It is important to keep your two separate at all times now, even when you are there as it can take very little time indeed to effect a tie and then they cannot safely be separated which would mean an injection for your bitch to prevent the pregnancy continuing which starts her season all over again........
You say you "feel" he would be an ideal candidate for breeding but really it takes lots of experience to know that, you really need to either show him and see how he does under several judges or at the very least consult someone experienced in the breed for at least one opinion. The way that breeding works is bitch owners choose their studs, generally from the show ring, so if you are not out there they will not really be considering you. If you don't show and just advertise some other way it is probably fair to say you will receive mostly enquiries from equally inexperienced people who very often will own bitches not up to the mark that may even have been turned down by responsible stud dog owners therefore you really have to consider do you want your dog's genes to be perpetuated in rather low grade litters that are maybe placed without care in inappropriate homes. The only way to avoid this is to have your dog properly assessed before continuing further with any studding plans.
