Congrats on making Troy University, that's Awesome!! The Montgomery Recreation department has seasonal summer camp jobs you should check out. Here's job info, http://www.montgomerycountymd.gov/rec/how/job.html

I would look for jobs in retail, food service, or at your local rec center. Plus, if you want to work at all during school, you might be able to transfer locations if you aren't moving to Troy until the fall.
