I know you said that you don't want to do research, but you should consider the IRTA program at the NIH. IRTA stands for Intramural Research Training Award. It is a program specifically for people who are applying to medical/graduate school, so you can actually get a lot of help with your application while doing paid research at the same time. You apply on-line, and labs review the applications and call people who they are interested in. People usually apply in the spring so they can start in the fall and work for an entire year, but I applied around October, started in February and worked until med school started in August, so the amount of flexibility is determined by your lab. I got three calls in December. One lab wanted me to go to Bethesda for an interview, but the other two labs interviewed me on the phone. They know that you're applying to medical school, so there is no need to hide anything, and everyone in the future will be very impressed that you did research at the NIH.
I'm not really into research, but I loved my time there, and it beat the hell out of the job I had waiting tables. I got more money, more respect, and it helped my med school application.
