Older woman looking for a Yorkie in Salt Lake City, Utah

Arthiritic older woman needs a small companion. I would love to get her a thin haired yorkie pup, that she can pamper, and love. She wants a puppy that would come to  be happy to curl up on her lap, and get and give kisses. I am  on social security, so i can't afford a lot. I can't ask her to help, because i would love to surprise her with a companion that will love her as unconditionally as she would love her new companion. Is there anyone that could help me to make a disabled woman's dream come true?
