Replying to Internet Service Providers in California? (LA)

So I'm going to be moving to LA in about 4 months and am looking to set up an internet connection for when I arrive. I haven't had much luck with Google search.

Right now I live in Canada so I really don't know anything about American ISPs. My question is:

What service providers are there and how much does it cost on average?

Right now I pay the equivalent of about $60(USD) for a 60GB dl cap and 10mbs dl speed. Is that comparable to the US?
