Kindle Cover Design
Here is a resource someone just shared with me. I have no connection and have not used them myself, but the service looks useful:
Go On Write Pre-Made Book Cover Designs
Go On Write. The Pre-made Kindle / eBook Book Cover Depository.
You can choose a pre-made cover, and then modify it to your taste. Extensive changes are an extra fee. After you purchase, that cover is taken off the market.
The good thing about this site is the pre-made covers give you a starting point. When you get a custom design from scratch, sometimes it is hard to communicate what you have in mind. Here you can use the pre-made cover as is, or have them change it to your liking.
If you are a true DIYer, you can still get good ideas on what a good cover looks like. Get inspired, but don't steal.
But why DIY? For a low price, you get a good cover and you are up and running.
