I've just read your other thread. Not sure what you've decided, but cycling fish-in is not a bad option. I've done it personally, and had no adverse side effects. It did take 8 weeks, however, because I was very strict with water changes to keep ammonia levels down (50-75% once every 5 days in a 5g). I also didn't seed the tank at all.
If you have an established tank to take filter media (a bit of foam) from, your tank will cycle more quickly. But it's really not that big of a deal. Your tank will cycle eventually, with minimal effort besides water changes. It's really not as hard as people make it sound. You don't have to do much of anything!
You said you'll be moving the tank at the end of the semester - if you try to preserve as much of the filter media and substrate from your tank as possible, you may not even have to recycle after the move (or it will take a VERY short time for the tank to recycle). The water isn't important, it's the bacteria in the filter and on the substrate that is (which would need to stay wet in tank water during the move).
I don't know how you plan to do your water changes, but I know you are on a budget... if you don't already have a gravel vacuum, a regular bubble tube will serve you well as a siphon. It's like $2 for ten feet of tube. All you need is that and a bucket!
