How can i create an spotlight effect??

 so im making this animation for an school project and i really need help making an spotlight effect,

basically my idea is this:

The scene starts and its complete black until it fades away to show both the background and the circus logo, at the same time tho we can see 2 spotlights moving around showing the circus logo off

i have the scene ready but id just like to know if anyone can help me on making the spotlight effect.

thank you so much for taking the time of reading this, wish you all a good morning,afternoon or evening.
