If you just wanted to jump once...go tandem with an instructor for about $125-200 -- more if you want it videotaped.
If you'd like to take it up -- your college club is a great place. UF had the "Falling Gators" -- but I'd gone way before I went to college, so...
I've taken the AFF (accelerated freefall course) -- it's very demanding and runs approx $1250 for 7 jumps. Once you complete those, you need a total of 20 solo jumps to get your card which will allow you to rent gear/jump at almost all dropzones. If you fail a level, be prepared to shell out more cash to retake -- I had to with the 5th level.
Another course is longer (I think 15 instructed jumps) and starts static line and is probably the way to go if you're not very athletic or have a hard time picking physical activities up.
It's a great experience and well worth it, even if you only do it one time in your life.
Good luck,
AJ
