$34 for an estimate? Wow... :o
If it is going to cost less ordering the part yourself, I would definitely go with that route. Keyboard replacement on laptops is trivial since, these days, the component in question is designed to be easily replaced. It's a job you really can't botch on, unless the laptop itself is horridly designed.
Also, doing it yourself means you're spared from having to leave your laptop at the shop for any extended period of time. Granted, this would depend on your school's computer center, and how they handle minor repairs. Some computer stores will be happy to do very minor part replacements on the spot, and won't ask you to leave your machine with them until the part comes in if not necessary, although I'm not sure if it is the case with the shop you are dealing with.
