Hi and welcome to YT!
I'm sure you will get the perfect Yorkie meant for you, you just have to be persistant and patient. I know, easy for me to say, huh?
Yes, Yorkies are costly, but there is alot of money involved in caring for them and raising a litter...at least there is alot involved when it is done
properly. There are lots of scammers out there so just be cautious in your search. You have definately come to the right place for help looking.
