Can of tuna or marshmallows in a live trap. Approach trap very slowly and calmly with an old blanket or sheet held up concealing your approach to trap. Be sure to keep this between you and the skunk. Slowly cover trapped skunk with that blanket. Take trap to pond or deep puddle and slowly lower trapped skunk and submerge for more than 5 minutes. Done
A live trap is the way to go.
Put a large heavy duty garbage bag over it. Preferably black and thick (that's what she said)
When you set the trap tie some rope or cord to the handle and string it through a small hole in the garbage bag.
When the skunk is in it, slowly approach and ease it into the bed of your truck. Don't let the skunk see you and try and move slow.
Worse case scenario it sprays, but not on you.
Lower trap into nearby water source. Drink a beer or 15. Retrieve, dump skunk. Repeat as necessary.
