| Although I left the radio business in 1989 after 20 years, I might be able to help.
Advertising rates are *usually* based approximately on the number of listener impressions you'll get. Popular stations are more expensive per commercial than less popular stations. Morning "drive" time is *much* more expensive than the middle of the night. The cost per commercial varies from market to market; you might pay thousands of dollars per commercial in LA, but only $50 per spot in West Podunk.
You'll want to pay close attention to the demographics you want to reach. Who is your target audience? Age range? Sex? Race? Economic class? Each station will have different reach in different demographics. I remember a story years ago where a company wanted to reach something like 10 specific individual people in the New York City market. They researched the tastes of those individuals and placed a total of six commercials on the radio station those 10 people were most likely to be listening to. And they reached them. Amazing. Anyway, you need to define your target.
Then you need to consider how often you'll reach your target. It usually takes 6-8 impressions before a person will remember your message. This means you need to buy enough commercials so that most of your target audience will hear your message at least 6-8 times. [Check around: You'll find people who can STILL SING the Winston cigarette commercial, even though it hasn't been on radio or TV since 1967! Or the "I'd like to buy the world a Coke" jingle from the early 70's. That didn't happen with just a few repetitions.]
You'll either want to work with a reputable, honest radio salesperson who can help you through this, or go to an advertising agency. The radio person probably won't charge you anything, while you can expect the ad agency to cost $$$. These are the people who can help you find your desired target audience.
At last, it's time to start putting your commercial(s) together. Often a radio station will help you with writing and production, often for free. If you make a commercial that will run on other radio stations there may be a fee.
Effective advertising isn't cheap, but it pays.
