Sorry to say, advertising isn't for amateurs. It's a place for us pros. I'm a professional graphic designer, and I am part of the marketing mix. It's also composed of writers, people who analyze demographics, and a whole bunch of other specialties. No, it's not easy, and no, it's not cheap.
To get customers to respond to your advertising you have to engage them on a positive level. If you don't believe that can happen, you are only noticing advertising that causes people to turn away. There's a whole industry of people, like me, out there who supply informative, meaningful, and beautifully-designed advertising to customers every day. We are well-paid because what we do works.
One of my students many years ago said that "Good Graphic Design is invisible, and only the message remains." And if you can't see good Graphic Design, or good advertising, that is why. We don't want you to try to swat us away like flies, or frame our work in a museum, we want you to know about a particular product or service.
