Hello, Welcome to YT Raean! Your in the right spot to do your research.
Good for you for taking the time to learn about Yorkies before just going out and getting one and then your like "ok I have this little furbundle, now what?!?!?!" lol! Any questions feel free to ask!
I am sure you found the for sale section by now, just keep looking the right little guy/girl will find you!
Good luck!
BTW are you looking for a male/female? what age?
