Where to seek translations of research articles I am collecting a large number of research articles from the historical record on a particular topic (comparative prime number theory). A good handful of them—about 10-15 or so spanning the 20th century—are written in German.
How does one go about (seeking or) soliciting translations into English of full papers, on this scale?
The translations don't have to be utterly perfect, but they should be professional-level translations—meaning we should be confident that mathematicians who read the English translations should get out of it the same mathematical content that someone reading the German original would get.
 A: Like you, I struggle to decipher  articles in German.  The older  influential  articles (before 1980) were all translated in Russian by top Russian mathematicians . If you can read Russian I highly recommend  these translations. Often they are better than the original since the translations occurred several years after the original publication and  they  often  include  as appendices  surveys of  what happened since the publication.  Many typos  and mathematical errors  in the original were corrected, and sometime in the footnotes you can find sketches of different arguments.
Another approach I  am using relies on Google Translate. It   has improved  considerably and I have used it successfully to read German articles, one paragraph at a time.   The translation is not perfect  but close enough so you can figure out yourself the mathematical arguments.
A: Elsevier offers a translation service at a rate of € 0.22 per word for a German to English translation. They promise that the translation will be at the level suitable for publication in one of their professional journals, without the obligation to actually submit to one of their journals. You might try them out. 
I know, this is a for-profit company, but I don't see how you can do this with volunteers, without payment.

A different issue is how you will handle the math. You could simply OCR the German publication and provide the translator with the German text without the math, but in particular for inline symbols this may be confusing. I have in the past used InftyReader to convert a scanned document into LaTeX, including the equations. Some post-processing is needed, but it might be an efficient solution.
