dont know of anywhere with specific openings but here are a couple radio stations/people you would want to contact
http://www.sportstalk980.com/main.html --> wtem 980... local sports radio outlet. Used to be an ESPNradio and the only gig in town til dan snyder started up xxx.
http://www.xxxespn.com/ --> 92.7, 94.3, 730... espn/redskins radio outlet owned by dan snyder, owner of the redskins, good station but their coverage reaaaaally sucks
www.wjfk.com --> my favorite local radio station, your average mantalk radio. I am a big fan because they just dont play other peoples syndicated crap they do live shows all day long (and everything is streamed/podcasted for those not in the DC area). If you like talk radio and youve never heard of big o and dukes you def need to check them out.
http://profile.myspace.com/index.cfm...endid=33293548 - this is the myspace of the guy who produces the big o and dukes show (and has his own weekend show). I know he is a big blazer fan, maybe he can help a brother out
www.dcrtv.com --> rumor website that covers all the local tv/radio outlets. i think he used to have a classified section on there with help wanted ads and the such
