Job Application

[Chad]

What are some good sources that you have made, to show an employer when applying for a job application?
I'm planning on getting a job preferably with my school which is security for all the schools in the town. High school (1), Junior High (1), Elementary Schools (3), School District Offices (1). There are probably around 3,000 computers throughout all the schools. Probably more if you count all the laptops and computers not in use. I was planning on making some useful and helpful tools for the school as well. Probably not to heavy on for showing programs and such but more on showing how computers work and what you know / understand about them, etc etc.

My second choice would be like what Matt does. Software Engineer in some company.
Any ideas on what to provide?
