Purchase black and white fashion videos

Hi there - I hope I’m in the right section.
We are wanting to purchase a short looped video, black and white of a fashion model, slow mo, spinning in a dress or walking down a catwalk or something similar outside under autumn leaves etc.
We are happy to purchase but we only need a short looped video and wondered how we can get this for our website.
If this is not on offer via you, are you able to provide a name of a company who may already have one in stock.
Thank you
