Purebred Miniature australian shepherd for stud

My little boy's all grown up now, and up for stud. He's finally figured out he's a man. He's a minimal blue merle, diluted black tri-color. His eyes are brown. His ears stand up, and he does have a tail per my request when he was born. His father is an international champion, both parents are from Turtle mountain miniature australian shepherds (miniaussi.com). He has a wonderful temperment, absolutely adores children, even though I dont have any, great with dogs, cats and my other pets. Soft mouthed, actually finds escaped snakes and retrieves them(has done this twice). Below are some photos of him along with photos of his parents. He is a member of the ASDR. Mini aussies are not yet recognised in the AKC so he is not AKC registered. His father was a toy at 12.5 inches, mother was a stocky type mini. He's tall and lanky at 14 inches and 17 lbs

Asking a stud fee of $500. I am located in Vacaville, Ca, but could look into shipping(friend does this with her bulldogs). He would be breedable to toy, standard and miniature.
