Images designed for business use for a Homepage banners

I need someone to design images that I can use on my website as banners. Images HAVE to be either licenced for business use or Free to use for a business like mine in the UK, and prove that this is the case. Basically, go to my website home page, see all the static banners there (from top to bottom) and refresh them to new images with the same dimensions (mobile & desktop version of the website). The images have to be jpg best quality possible with the small size possible. We try one image first to see how it goes and then we can continue changing all the images (banners) on the website. They have to be CORE VITALS friendly.
