Help pricing a motion graphic gig please?

Hi everyone,

I'd like to know how much to charge a client for motion graphic work, it's not my area I mostly do 2d/static stuff.
so, this one was very simple, a 15-second video with some text sliding& fading in/out effects. so I'm kinda not sure how much should this cost? don't wanna overcharge or underpaid, what would be a reasonable price for it?

Thanks
