One of my friends recommended a radio booker who basically charges $200-$500 every time he books you on a radio show. These are supposedly big shows that are either in big media markets or nationally syndicated.

Has anyone tried these radio show bookers? Are they worth the money?

I considered the DIY route. Kremer recommends a crash course + radio contacts database by Alex Carroll (radiopublicity.com). That site looks really spammy, but the programs he sells for getting you on the radio comes with a money back guarantee. Carroll also lists the co-creator of the Chicken Soup series as one of his clients.

Has anyone had any experience with these self-help radio booking courses?

Are there any magic templates for booking radio shows that everyone knows but me?
