Offshore software development has become a huge industry over last 30 years. Your friend can find a company or a team in almost any country that is close in culture and offer good price/value ratio. There are some do's and don'ts in this process, but he can find them on Internet easily. The most dangerous underwater stone to mention is intellectual property rights, especially when you do not follow all regulations. There are many others as well. I am in offshore software development for 25+ years and worked with USA and European clients, learned a lot of cross-cultural hints. Your friend better find someone who can help him in choosing the vendor and establishing relations with it.
