I am a skunk expert. Founder of the Brotherhood of the Skunk, an exclusive group of fellow terriermen who know from first hand experience.
To deal with your skunk: Live trap with a can of cat food for bait. Tarp over the live trap to pick it up and transport. Trap and skunk into river. If the skunk can hold his breath for ten minutes, release him to swim in the river. Otherwise on the bank for buzzards, crows or worms.
About the odor. There are three things I guarantee to work, nothing else will. It's July. What will work to remove skunk odor from the dog are August, September and October.
P.S. Open the can of cat food. Skunks are illiterate and cannot read the label on the can of cat food. Even if they could I doubt they would be able to open it.
