Electronic Production of Website Product Mockups

I have a group of approximately 392 digital files that I need converted into bird's-eye product mockups for my website. They are 5x7 and 4x9 (portrait and landscape) and 5x5 printable cards. I have attached an example of a mockup I created using Canva. I do not want all the cards to use the same mockup. Variety, creativity, and quality are important to me.
