Who do I call to get help with Skunk traps?

I have a big problem again this summer with skunks on my property. How can I get rid of them. They are coming in in the wee hours of the morning and I can't catch a glimpse of them, yet I see all the signs when I get up in the morning. In the past I have been able to see them after ten at night, but these are coming in after 1 am and I can't stay awake long enough to see them. How can I get a trap and what do I use to bait them so I can get ride of the problem. I have a stone wall by my front door that they have marked with scent. My lawn is destroyed and we have small dogs that I am tired of cleaning up from skunk smell.
