Hello and Welcome to YT. In addition to all the sound opinions and advice everyone else has given, I would just like to add that I went and looked at the site, also viewed the Yorkie puppies that are for sale. IMHO they are not good representations of the breed. When it's the right breeder and right puppy for you, you will know it. If you have doubts or questions, then I say trust your instincts and move on. Take your time and research reputable breeders and you will find your new baby soon enough. Best wishes!
