Help with Unity demo

I'm a college student who needs help creating a quick Unity model of a project I've been working on--this is a personal project not something that is required by any class. All I really need is like a 30 sec video file showing and opened box going along a conveyor belt, and then is stop at the end where a robotic arm (images attached) write "Thanks" on a piece of paper and then drops it in the open box. Done. It does not even have to be detailed at all. In fact I'm in a pinch and need it done as fast as you can so it literally doesn't have to be anything fancy. I will also upload an image of how far I've gotten with it using unity. It'd be better if I could talk to the contractor over the phone just to go over it. Someone who's skilled in Unity could probably finish this in 30 min. Thanks, Jason
