I Need a way to get My service out in the general Public

I have a free service for companies. We do Removal and pickups of unwanted items. We do this for many companies from Tv stations to Hospitals. We do as needed pickups and full clean outs. We never charge a dime. Im blown away by the fact that every company that uses are service signs us for all of their locations. They all tell me Im setting on a gold mine. I do tv stations and they all say they will do a piece on me but the folks that put the shows together don't find my service a interesting piece for the people who watch the news. I do the biggest paper in my state and they cant get me even an small place in the paper. I saved them like 40k last year alone. I started my company to help American Business save money and grow. I want to help the economy and the news is always saying "Who is going to help" , Well Here I am !!! I want to get some advertising so that the companies that need me can find me. I talk to a lot of companies and they always say that once the word gets out Ill go big time. I cover a few states and its not hard to find the companies that need my service. They all need it but some are months and months out. I want to advertise so the companies come to me and not the other way around. I have a huge following from word of mouth. I just want to get exposure so I can not only help companies but grow as well.
