This is an awesome networking hack! If you're looking to "meet" a bunch of employers, check out Hired - http://join.hired.com/x/WF25Mp. We placed someone with a very similar background to you (18 years old, web dev) a while ago. Everyone loved him, they'd be excited to meet you too.

Side note, I'd be happy to chat over coffee and discuss the valley, opportunities, and how to not get screwed over, regardless of your interest in Hired.
