I know nothing about this breeder. I did go to their web site and noticed that they are willing to ship a puppy at 10 weeks old. This IMO is too young. Here are a couple of useful links with a lot of info. on purchasing a puppy. I hope this helps and good luck with your search.
teacup yorkies, baby doll, miniature, micro mini, teddybear or standard yorkie puppies do not exist http://www.yorkietalk.com/forums/fea...ead-first.html
