Chris,
One suggestion.. If you have time/availability in your schedule, try to reach out to area company's and offer to be a free intern. Explain to them you want to learn! Get yourself a LinkedIn account and network on there. Try to do research to find names of marketing professionals in your area.
I have a guy working for me today that called me in his last semester and said he needed an internship... i could not pay, but needed the help.. he interned for the semester, got a job in the industry pretty quick after graduation because he had the experience on his resume' . Also, dont limit yourself to what you consider "marketing". Look in the sales community as well. try to find some sales professionals that you could offer help too. even independent reps.
I know about 5 independent sales reps in Columbia, MO that would all consider some "free help". if you have time available.....

send me a PM if you have interest in helping some independent reps out... (all in hunting/outdoors industry)..
