Been there, done that, on getting label service. I did everything from sending out official requests on college letterhead to phoning. What is comes down to, if you aren't an officially licensed FCC FM or AM station, service will be hard to get. We were an FCC station, but AM, and even though each label has a person strictly to deal with college radio, NOBODY wanted to deal with us because they didn't get that college radio can be other things than FM, 100 watts, between 88.1 and 91.9.
I recommend strongly contacting Lost Highway. They are a division of Universal that deals in AAA and alternative. I've been in pro radio now for, damn, 18 years. and Lost Highway has been the most responsive label I've ever dealt with.

One thing that will REALLY help is to get on a charting publication like Radio and Records or NAV. There are college equivalents, but I don't remember what they are, although joining IBS (Intercollegiate Broadcasting System) would help. If you want to pursue it as a career, go to the IBS convention every year and network.

And keep in mind, professional radio will be completely different.
