About 8 years ago, someone came out and cleaned our vent to the dryer
since it was clogged. My vent begins in the laundry room and travels
about 30 feet and exits out the wall on the side of my home. My wife
was home, so I'm not sure how it was cleaned out.

To clean this myself, what tool or tools would I need and how much
would it cost?

First thing you need to know is what type of vent pipe do you have? If it
were that tin foil type, it can be very easily be damaged with a vent
cleaning brush.
