A month is plenty of time to get a puppy adjusted to new surroundings and work rigorously on a potty training regimen. One suggestion might be to get a slightly older puppy (in the range of 4-7 mths, or even a little older if you're willing. Honestly, whatever age yorkie you get, they're ALWAYS like puppies.
Another suggestion would be to make sure that you DO leave her alone from time to time. It will be tempting to take her with you everywhere and stay home with her all the time - but she needs to adjust to you not being there 100% of the time for when you do return to work.
But this is all secondary - first - find a good breeder and the right puppy!!! Then post lots of pics on here!! If you've got the means to care for a yorkie puppy and an understanding of this breed, I say go for it!
Good luck in your search! And welcome to YT!
