Radio Advertising: 52k listeners hourly

Hi. I am a 22 year veteran radio talk show host, currently hosting an overnight program in the Norfolk, VA, market. We have a fantastic audience on our home station, WHKT, which can be heard as far north as Philadelphia and as far south as Florida (weather permitting, I should add). The program also proudly has an internet audience that averages about 52,000 listeners per hour on our internet stream! Not too bad for an overnight radio program.
We are offering advertising as follows:
two 30 second commercials per hour, four hours nightly
one personal endorsement per hour by the program host
an advertisement on our official website,
