2D game art backgrounds

We are building a video game and interested in purchasing peoples 2D backgrounds or assets that they have for 2D games as we would like to add animated sprites and lighting to our game. Here is an example of a high quality background https://assetstore.unity.com/packages/2d/environments/bundle-hand-painted-backgrounds-72880
If you have assets please reach out with an offer and example of them. I have attached an example of our current game background which could use some lighting and animated objects. Also, assets we purchase or create would need to be in a similar theme
