Sounds like a couple hours of labor. The genuine factory part is probably around $100 or so. You can get an aftermarket at Autozone for around $35. It's not a very difficult job. I don't recall needing any special wrench. Now the harmonic balancer remover tool required special screws that were tappered at the end. They didn't come with the reccomended tool. I had to improvise but that was too difficult either.
