Border Collie Adult Dog Wanted

Hi, I'm a dog lover from Vietnam, especially intelligent and friendly breeds such as Golden Retriever, Labrador Retriever etc...Of course, I have 3 for my own - 2 Golden Retriever and 1 Labrador. I really love to play with them and teach them tricks, I do my family business, so I have plenty of time for them. There are many Retriever Breeders in my country ( Vietnam) so I could have one easy. But, not one of them is Collie breeder, there isn't any Collie seller too. Based on Vietnam dog lovers's statistic, there are only 2 Border Collie in Vietnam, one of them belong to a Japanese... :(( Now I'm looking for Border Collie breeders who can help me. I want a couple ( I can't buy just only one male/female then one day, he/she will going crazy because there's no mate for him/her), from age of 4 months old up to 1 year old( have had vaccinated for common diseases and rabies).. One more thing, I don't have much money, please don't cut my head off ( I'm sure if you could sell me, I will tell my friends about your company, corporation, dog-farm etc... and you can expand to my country, a potential market :D Thanks, and goodluck to you all
