I have experience in both marketing admiminstration and outside sales but my recent work experience has been related to customer service, in a call center environment. I want to only be working in the marketing field though, that's why I went back to school for it.

trying meeting marketing folks for info interviews on LinkedIn http://www.linkedin.com/home or professional groups in your area. you might even try volunteering or interning to get a foot in the door. also work with your school placement office as they often have connections.
