PLAY MY RADIO STATION PROMO EVERY HOUR OR X SONGS

I NEED A SCRIPT TO PLAY MY RADIO PROMOS AND RADIO ID'S AT THE TOP OF THE HOUR OR AFTER X NUMBER OF SONGS. THIS SCRIPT COULD BE DONE IN PAL, JAVASCRIPT, PHP, JQUERY, ETC I WANT THIS SCRIPT TO BE ABLE TO CHECK WHEN IT NEEDS TO RUN AND THEN EXECUTE THE AUDIO FILE AT CERTAIN INTERVALS. I NEED SOMEONE WHO CAN BEGIN WORKING NOW AND FINISH SOON. I AM LOW BUDGET IF YOU BID OUTSIDE OF WHAT I CAN AFFORD, YOU ARE WASTING YOUR TIME.
