From Pocket Work:
The purpose of this application is to connect interpreters and their clients fast, allowing utilization of their services even if they are in two different countries or continents.it collects professional translators and checks the references submitted by themfast (because you avoid searching for the translator through the Internet and the negotiation about paying)low price (because phone expenses are prevented by the IP-based connection / there's no any phone costs)it is perfect for solving extreme situations (e.g. if you cannot communicate with someone when you are abroad)it is an easy money making way for the translator because he can change to "on line" state any time in his profile, and he can receive calls independently from his location.it allows mobility for both parties because it is much easier to take your smart phone with you than your PC.
