Things I should look for in a new job

So I currently work in a help desk environment as a contractor. Currently I?m working on my A+ cert and have a BS degree but my only real work experience is this job in help desk. I would like to move towards a Sys Admin position as my end goal but I?m curious as to what some good jobs I could be looking for in the interim. I plan on going after my Net+ and then my MSCE after I finish my A+ and am just curious what should I be looking for in a job that would help me move words my goal.
