Ask HN: Outsource support to US?

I'm based in Indian and will soon release my SaaS app, and since the primary audience will be US and European users, I'll need to provide support during their daytime.

I wonder if there's any US company/service that handles phone support for non-US customers?

Ofcourse, when we can afford we'll setup an office and hire someone in US but for now we're looking for a cheaper solution.
