What should an "ambitious non-technologist" do with a promising Start-up idea?

I'm a college student with what I think could be an enormous start-up idea (I know, I know). But seriously, enormous. I'm not a coder and I don't know any despite doing an extensive comb of campus. Is there a place or trusted website I can pitch ideas and get tech people? What are the most efficient steps for someone in my position? Thanks.
