I realize there are already plenty of threads here covering employment agencies and websites, but as I plan to be in Switzerland in September (and considering the present economic/employment situation), I'm wondering if anyone can suggest one or more agencies or HR departments that are particularly active these days, particularly with respect to IT (web development/programming) needs.

While I may not win any interviews, I'm mainly interested in making (if not meeting) a few contacts for networking purposes, perhaps to build on later. Any suggestions will be appreciated!
