Contact your municipality, town, or county office, pest/animal control department. They should be able to advise you, or refer you on to a service that will set traps and remove the animals.
Where I live, Animal Control does not handle skunks unless in distress. Here are some methods you might try.
Found one in my fig tree the other night. I just shooed him or her on their way by shaking a branch on the tree.
Step 1: Remove food sources around your home, such as pet-food bowls and low-hanging bird feeders.
Step 2: Place all trash in cans with tight-fitting, locking lids.
Step 3: Eliminate any insect infestations you have. Also be sure to take care of any rodent infestations, as skunks will eat small rodents.
Step 4: Remove piles of brush, wood or other debris in your yard that could serve as a hiding place for skunks.
Step 5: Use wire mesh to seal any openings in or around your home that skunks could be using to enter crawlspaces, basements or other areas.
Once you’ve eliminated food sources and hiding places, your home will be less appealing to skunks; however, this does not mean they won’t come back. By using an effective skunk repellent, you can keep the skunks away.
