Main problem is that someone in US just can't get the relevant info on 99% of the overseas teams out there. The ones that you first google out are usually the ones who advertise the most and who generally always oversell their resources, and thus produce really bad results. Experienced small teams usually already have a number of clients, work hard and are not that visible or fast growing. So try playing smarter and avoid corporate outsourcing channels, and instead reach out to overseas developers' communities on twitter and conferences and contact developers and teams directly. You'll get much better results.
