Lay a few possums out in a bait pile with cameras. Around here Nothing feeds on a possum xcept The bugs

Per skunk?

If you are serious about making money or running it as a real business, you will need to charge a fee to look at the job, a fee to set it up, a fee to return and then a per skunk.

Or at least something along those lines. The average fur trapper loses money doing work on other people's problems

If you are working for a "town" chances are, you will be required to have some sort of liability insurance. Even if they don't require it, I wouldn't set a trap on town property with out it.

These guys will regulate you out of business before you get started. LOL

All of the municipalities that we have worked for over the years have required a copy of our liability insurance and many asked for a copy of our workers comp policy. They won't carry you on their liability in our state as of yet.
