Looking for a long haired, preferably calico kitten. Does anyone know of anything?

I'm looking for a long haired (Maine Coon or similar) kitten that's preferably Calico, but will consider other colors. Gender doesn't matter, preferably spayed (but will consider not), with first shots, and tests negative for communicable feline diseases (we have another cat). It doesn't have to be ready for Christmas, it's not a gift.
