Hello Ariana,
PR stuff :
*Do charitable things for the community (i.e. Toys for Tots drive, coat drive for needy families) and publicize them EVERYWHERE to get a better turnout.. like The South Texan (TAMUK newspaper), The Kingsville Record, ask the TAMUK radio station to do on-air promotions of your event (they will do them for free)
*I know the football season is almost over, but maybe with the opening of the basketball season you can put an ad in their game programs with something like "Delta Phi Epsilon supports the Javelinas!" (Sounds kind of corny, but the sororities here do that sort of thing in the football program and it really helps get your name out!)
edited to include: Check with the radio station on campus (K9-11) to see if they will be hosting any events. When I worked there, they did a couple of events with fraternities on the campus. For example the fraternities helped pass out drinks, flyers, etc., and wore their letters, so you're not only helping the radio station out, you're getting your name out and having some fun too!
Best of luck
