At my school, our rush is between $300-$500 total. Not a huge deal, because we have no frills recruitment. No costumes, no elaborate decorations, no major food. At the colony I advise, they cannot spend more than $800 on recruitment, $400 of which is food. BUT, they can use anything from their homes that they want, and it doesn't count in the budget.
With $120K, I could throw a killer recruitment party...like for instance invite Dave Matthews to sing!
