I looked back at all your posts you started and - yes, you have had a time. You know about AI, you like to negotiate terms, and you have checked out studs. You seem new to breeding, but you are not. I think you might want to check out this site for Canadian yorkie Assoc.
Canadian Yorkshire Terrier Association and may lead you in the right direction - right stud, breeding ethics, etc.. May be your best choice.
Like my dad always told me - "If you want to do something - Do your best!"
