Best way to get instructions translated?

I've decided I want to build the Roman liburna from this site: Mondorfer Bastelbögen

Regardless of my username, my German skills are limited to about four words. The PDF file is created in such a way that I cannot copy and paste the text into a on-line translator. What's my next step?

Any suggestions? Does anybody know of any OCR applications that work reasonably well on PDF files? Those that I've seen only allow the first page to be translated. I suppose I could break the file into separate pages ....

Thanks,
