Welcome to YT!
I know it is so so hard to wait, but don't settle for any dog when you know you want a yorkie from a reputable breeder. Continue looking cautiously for the right one, and maybe you can keep putting money away to save as you are searching...then your budget will grow as you are searching for your new baby. Just try to be patient...you'll be glad you did in the end.
I always recommend
www.ytca.org to start out looking for breeders. Good Luck
