There are paid internships out there, you just have to look besides the Student services job page. I did a paid internship over the summer while at UND. I didn't get it through UND, I went out on my own and looked for one. It was a great experience and gave me my first experience in 121 operations. I learned a lot and made a lot of contacts. Also, every single job interview I've had so far I was asked about my internship experience. And to show you how small the aviation world really is, I recently had an interview with a 121 airline (which I got through networking!) we were introduced to some of the management staff and I recognized the Director of Flight Operations right away, as he used to be the Chief Pilot back when I was an intern at this company. It definitely helped me that day knowing the Director of Ops, even though I didn't get the job! The point is, the SAMA conference will allow you to make many contacts and possibliy get you a job/internship!
