Hal, if you can get your hands on a .22, thats going to be your best bet where you live. Pistol or rifle will do fine.
I used to use this method for live trapping coons at my parents house, im not sure if it will work with a skunk, however. Take an empty, normal sized trash can and set up an 8 ftX6" board like a ram to the top of the trashcan. Leave the lid off, put some foods down in the can, and maybe on the ramp to the top. They will follow the food up the ramp, fall in the can trying to get the shit inside the can but wont be tall enough to get out. pop it with the .22 inside the can and there will be little sound.
srsly
