I don't work for this company, but after almost leaving Squarespace for its lack of multilingual ability I finally came across easyling.com. I have seen other similar systems mentioned here, but they were much, much more expensive and not as slick.
Balazs Bendeck at the company worked tirelessly to set me up properly and it has been functioning great. It takes no time to add new languages and has a seamless integration with my site.

If anyone has any further ideas I would love to hear them.
