Once you have a website, you need a translation. Sure, you can ask Google to translate, but I am really not sure your site will be nice to read and without mistakes. I am actually pretty sure it won’t be nice to read, and it will be full of mistakes. If you want to address your (future) clients in their own language, you might as well do it right! Dutch is my native language and I speak/write French and English very well.
This is not only essential for your (future) clients, but also for Google and the Search Engine Optimisation. As a web editor, I am used to write for Google, so as a translator, I do just that as well!
