Regardless, you should be able to copy/paste the text from the .pdf into Babelfish (or another online translation program). Unless the file is stored as images (or protected, in which case you may be breaking some copyrights), using the text select tool should allow you to put the text into a free translator.
Of course, if you're looking for someone else to do a professional translation, there are plenty of services out there that will do it... for a price. Otherwise, good luck finding a d20 and W40k enthusiest qui parle francais.
