Alexander, in the first place, we don't reply to breeder questions. In the second place, all but about two of the readers of this forum are from someplace other than Malaysia, so we have no idea about finding guinea pigs there.
The usual ways to find guinea pigs are to search the internet for pigs in your location, or to check the want ads in the local newspaper, or to ask at veterinarians' offices or pet shops if they know of any available pigs.
