If you leave a message on our South Coast Basenji Fanciers FB page, I can message you a list of our current breeders. As stated above the bitches only (usually) go into heat once a year and puppies aren't born until late fall/early winter. Now is the time to get in touch with breeders and find one that may be the right fit for you.
There are not many breeders in So Cal, so you may have to branch out looking into other areas.
