Just my opinion of course, but I think that if you want to hire a book cover designer and expect to pay under $100, you're going to struggle and be frustrated. It's not that a good designer can't knock out a killer design in s short amount of time to make the $100 worth it to them, but that's just so rarely the case. Designers can't read your mind. It takes time to go back and forth with a client about what they want/need. Then add in revisions? It just doesn't make sense for a designer to take on projects like this for $100 (or less). And that's even if you can find a designer willing to take the chance in the first place with such a low dollar amount on the line. A lot of designers won't even consider working with a client with a sub-$100 budget because there is a high likelihood that the time involved won't be worth it. My advice: Be willing to PAY MORE. TRUST DESIGNERS when they tell you what it costs. Good designers are not in the business of ripping people off. If you can't do either of these, take some classes or courses and watch YouTube videos and learn how to make your own book covers. You'll either learn and start saving yourself money or you'll realize that cover design is hard work and that you should pay designers for their skills and talents (rarely under $100). Remember, you're paying for the skill and expertise. Don't get mad when they make you a BADASS book cover and then you find out it only took them 30 minutes. You are paying for their talent, not their time. Thinking in terms of hourly wages can really mess people up, but think it through: Do you really want to pay a designer by the hour? They would be incentivized to TAKE LONGER and charge you MORE. Is that what you want? No, of course not.
