She's a beautiful little snake. I suspect the breeder wasn't truthful with you about her eating F/T. Baby kings can be pure hell to get started eating, so try not to be too hard on yourself. Feeding live will likely do the trick.
Remember to check Craigslist and/or the Facebook rodent breeder groups for local contacts. Also, check to see if there is a local herpetology society in your area - members may have suggestions. Check with your local zoo and/or any wildlife rehabs if you have either in the area.
If 4-5 days pass and you attempt another F/T feeding before you can locate live food, try braining the F/T mouse. I know you tried the peeling the nose trick, but braining them results in a more intense scent. Sorry for how yucky this sounds, but it isn't too bad on a F/T pinky: take a small nail or a pin and push it through the base or top of the skull, then squeeze until you can see some brain matter and cerebrospinal fluid.
I'm not a fan of putting pinkies in hot water because they 'cook' too fast, but for a really stubborn eater I do like to blast the pinky with a hair dryer for just a few seconds - sometimes that extra touch of warmth really helps, though the scent from braining may well be sufficient. I'd dim room lights, offer it on tongs, drop it right in front of your snake as soon as she indicates she's scented it, and walk away. My Gray-banded Kingsnake has been with me for going on two years now, and he has only recently started taking food from tongs; I had to leave it with him before. Best of luck! Once you get past this very frustrating barrier, you should have a little eating machine on your hands.
