Start CPR and use an AED.

Explanation:

By the time you get someone with more advanced training, the person who's in need of help's gonna end up dying, so the first and second options are out.

You don't send someone for the AED solely to get them out of the way. It's best to have help if you need to swap out during the procedure.  

The AED is foolproof and is designed to give you instructions on how to perform CPR and when exactly to stop and deliver an electric shock, so the third option is the best choice.
