We have good expriences with Tilti from Latvia.. we have worked with them in more then 20 languages and had checks done by other natives speakers afterward to check on quality.
http://www.tilti.com/From our experience it's good, fast and not expensive when compared to other translating agencies.
Their standard rates earlier this year were 14 euro cents/word (about $0.19) for Chinese (their highest rate) and 12 euro cents (about $0.165) for Spanish.
Other exotic languages like Russian and Eastern European languages cost 9 euro cents/word..
An effective system to manage translators may save a lot of time/costs.
Their translators usually work within our CMS, which has intuitive lists of things to do for every translator.
They just click the links in the list which lead to items to translate, translate it, click a button to submit it as translated and then they are returned to their list which became one item shorter. We do the word counts in our CMS and we pay per word.
If you'd like to try Tilti, my contact at Tilti is Olga Setinsone, Olga.Setinsone@tilti.com, she manages the translators.
If you contact them I'd appreciate it if you say hi from Damian Doyle
