10 second loop ready videos

I am looking for a collection of simplistic but elegant and stylized, 10 second loop ready video files. Please see image attached of what I have already created. I made leaves fall to the water surface that made slow simple waves. These video files will be used as templates for text and logos to be put over, so please consider having some 'negative' or empty space for something like that. I am looking for as many clips as possible and will be using this platform to hopefully establish a long term relationship with someone who can provide great quality work, but realistically for now, I would like anything from 3 to 5 clips. Themes for these clips can vary. I need tranquil environments (such as the reference pic for example). I need seasons i.e summer, winter, spring, autumn. I need themes related to disco, party and carnival i.e. using images of a disco ball, confetti, streamers etc... I need themes and iconography related to the medical field i.e using images of pills, test tubes, neurons etc... I also am looking for themes around awards like the Oscars and music industry. You can be as creative as you like as long as everything is elegant and aesthetically pleasing. For now, I am willing to pay 15 USD per HD 1920x1080 30fps clip, 20 USD per 4K 30fps clip, and once approved, I would need ALL rights to the clip and elements used in it. Some of these could end up being used commercially and I cannot have copyright issues with them. I will ask the artist to provide a signed document for these clips. Thanks!
