I would like to have a short social media advert produced that explains my website

hi i have a new website launching and i would like to have a short social media advert produced that explains my website and how it works, this would include instructions of how to use it and how it benefits the people using it, I would also like some video of the website that is edited , to show exciting and beneficial ways to use the website. I will have the website available for you to video and screenshot and get to understand the website before making the promo so you know exactly how it works. Thanks
