Reedsy. Reedsy has a bunch of professionals that you can hire to create a book cover for your novel. It's mostly free, (to use the app or website) but obviously if you get a cover from somebody you have to pay them. Its pretty expensive, so if you are on a budget, its not one of the best resources. but the price also depends on who you hire. Another resource is Bookbaby. You can also hire people there to digitally design your cover. (I'm pretty sure that the price is the same no matter who designs your cover.) Bookbaby is also pricey, though. Hope that helped!
