Digital Art For A Webnovel Cover

Hey all,

May not be the best sub for advice, please redirect me if I'm in the wrong place.

I am a subpar digital artist. I use procreate and struggle with it, and can sketch moderately well on paper.

I, however am a writer by trade, and I want to publish a web novel. I don't think my art is good enough to serve as covers for the high quality work I want to produce. Again, I can make decent sketches, but I struggle deeply with rendering and all that.

Also, I'm broke as shit. This is a passion project, and I can't really pay anyone at the moment. Would there still be people willing to collaborate with me on something like this or is it just a pipe dream?
