Nft collection

Hi, I already have 50 nfts but need to make variations of them changing the background or other very basic thing. Also I need a header image, icon image and a vertical banner, all very basic, I will provide the image and idea. To end I would need a simple landing page for the nft collection.
It is my first project and it can be crappy and bad quality, I will just look for the lowest bid, my goal would be to gain experience.
Kind regards
