I would also check YTCA (Yorkshire Terrier Club of America) or AKC and look at the show events and see if there is someone near your area you can contact. This way they will be close to help you search and see the dog - to give you help. You should also go to the local breed or all breed dog club in your area. There are people there that can help you to. Best of luck! Sounds like you are doing good.
