Media Outreach -- Pitch an author/book for interviews/guest spots

We are currently working on a tour in the U.S. for a book launch and have sent email inquiries to many media outlets - newspapers, radio, TV - in various cities. We are looking for someone that can follow-up on our requests to these outlets with telephone calls to these contacts to pitch a proposal to get an interview for the author for an article or guest spot for radio/TV shows (local talk and morning types of shows). We have contact names and phone numbers for most, but for those we don't have names, we'd also need help in determining who the person to speak with is and to also have someone talk with them and pitch a potential article or guest spot. There are approximately 50+ media outlets that we would like to have contacted and we will provide a script for the pitch. We would like this project to start immediately and would like to inquire as to cost for this project and whether it would be an overall price or hourly cost. Please advise me of your availability and rate at your earliest opportunity. Thank you. Jo Sudore Worldwise Publications
