Have you assessed any other methods? The EPiServer-LanguageWire translation plug-in created by Inexor will automate all translation workflow processes without the need to leave the EPiServer environment - it's a one-click solution. Translations are handled by human subject-specialists. This should relieve you (or your clients) of the headaches associated with integrating translation into the EPiServer environment or managing multilingual implementations.
Alternatively you can create your own API - we can send you some DLL files for you to integrate.
Please let me know if you need more information on this recently released module. I'm happy to give you a call to discuss.
All the best,
