How to do a commercial for a school project?

I have to do a commercial for telephone like in the 90s or 80s but I don't have any old telephones that I can use for a prop and I don't know anything about video anything all I have is an iphone and I don't know if you can edit videos it and is there like any programs on the computer I can use to make it look old school

Old school? Create a cardboard replica, what a stitch! Or go to a local second hand store and ask if they have any old phones to borrow for an hour or two, I bet they LOL and give you one
