High GPA College Student unable to find summer job, need help.

I am currently going into my Junior year of college at a Public University known for their business program, and I am studying Management Information Systems which is a top 5 public ranked program. I am in dire need for a summer job, and have applied to a dozen or so local businesses most of which in the retail and food services industries. The problem I am facing is that I have yet to hear back from a single one of these jobs that I have applied for and it is due to a lack of experience. It is extremely frustrating as I have worked my tail off at college thus far and have a cumulative GPA of 3.93, however this is not considered by many of these employers and the system of automation seems to automatically count me out due to my lack of experience. I have worked at a number of music festivals (volunteered but some paid) however the way they have experience set up in these applications I can not include these in because I do not have the names of my supervisors. I only have another two months of summer left, and I was wondering what I could do to improve my chances of finding a summer job. A little more information is that I am staying the summer in the town that my college is in and could continue to work after the school year begins.
