Japanese to English, technical document translation

I have a series of manuals/user guides I need translated from Japanese to English. There is a requirement to understand the sort of technical language unsed in these documents ( see sample page ). I will supply PDFs of the scanned documents, and Word files containing the content for editing ( these documents have already been run through an auto-translation service as a starting point ). I require the Word documents be corrected for the ( many) errors in translation, keeping the format as close as possible to the original documents.
