Have you tried Babelcube?

Do you want to sell more books? Are you trying to reach a larger market? Would your books sell more copies in foreign markets if you had them translated into that language?

Babelcube could be the answer to all of these questions, and the great thing is - It's free!
Babelcube connects writers with translators. It's easy to use. Just post your profile, upload information about your books, and wait for independent translators to contact you. For authors, there's no cost up front. Babel cube handles all of the details and splits the profits between you, the translator, and of course, a small cut for the house.
Commissions are based on how much revenue your books take in. Babelcube receives 15% for brokering the deal. Your split ranges from 30% to 75% depending upon how many copies your book sells and the revenue generated. You receive 30% of revenues for sales under $2,000, and 75% for sales over $8,000.

They currently offer translation services into Spanish, French, German, Italian, Portugese, Japanese, and Chinese. 
I uploaded my profiles today, and posted five books that I would like to see translated. I will keep you updated on how things progress.
