What is the job of the speaker?

Hello everyone and welcome to the town of Brantford. I am Phillip and my job today will be to show you the sites and attractions of this fascinating city. We will start the day off by visiting the glorious Rosa Tower. After that, we will visit the oldest church in Brantford. From there, we will walk along the Foster River and have lunch on a cruise ship restaurant where you can view the pleasing scenery of the river. At the end of the day, we will go to the town’s shopping area. Once there, each of you will be accompanied by a personal shopper who will help you find what you want and help you negotiate a good price. And please remember to tip these aides after you’ve done your shopping.
