Need help with my book cover

Hi! I am a new author and am looking for a book cover artist. I currently do not have much money and wouldn't be able to pay the usual rates, if at all. It is a sci-fi book about spiders living in a space station. I can draw on paper and have a design, but I am not good at making anything digital look very nice. I will add you as the cover artist in the print info page of the book itself. It would be for publishing on kdp as an ebook. Thank you for your consideration.
