College student looking for med sales advice

I'm about to start my last year of a B.S. Physics program. I have an emphasis in medical physics and have been interning at the local Radiation Oncology cancer center. I love the field of medical imaging, but realize the patient interaction is not for me. Transitioning into medical imaging sales seems like a logical choice. Working in the hospital, I've gotten a feel for what rad techs, doctors and patients value in their equipment. I do not know anyone in the medical sales field, though, so I'm not entirely sure of the best way to search for an entry-level job (or companies that are particularly good for recent grads). I'm not looking for the highest-paying job or the loftiest title. In this economy, I will take what I can get, even if that means an internship for piddly pay. I'm well aware of the competition, which is why I'm trying to start this process now. I have several months before I have to 'hit the pavement' but advice from insiders is greatly appreciated!
