Finalize the print files that are already in IngramSpark and Amazon KDP

Please reply to these questions as otherwise I know you didnt read the post: How long will it take you and what would you charge? I am not dumb so dont try telling me this takes hours as it wont. I just dont have the experience with KDP and IngramSpark hence want to delegate this task... (Budget: $10 - $30 AUD, Jobs: Graphic Design, Publishing)
