Graduate With a Profit : Make Money While in School

Rent a large van and simply shuttle people around campus during graduation. Hundreads of students are going to be graduating, and each student is going to have their family and friends there as well - what is the common factor? They all have cars and need to park somewhere. However, all parking lots on and off campus are going to be packed so what do you do, help them get from point A to point B! Buy business card magnets and stick them on apartment doors, make fliers, signs, do anything to get the word out. It is a simple concept but something that everyone (especially the university) will appreciate.  This should be relatively easy way to make money during the graduation season.
