Hi there,
I'm a professional systems engineer who also offers technical authoring, proof reading and editing services. I am a native UK English speaker, and also a software engineer who works with PDF and Word documents at a programmatic level, and hence, understand both products very well.
Having skimmed through a couple of the documents, it is clear to me that these are engineering manuals, and hence would be within My domain of technical expertise, as an engineer.
This task is actually relatively simple, as long as all data is available, for insertion/editing in the final (output) Word docs.
I have up to 7- 10 hours a day available at present and could do with the income; and, have an excellent eye for detail and accuracy. I would be inclined to proof read the end result, against the original PDF documents, to ensure accuracy in conversion AND to correct any typos/grammatical errors in the original documents? (If that is needed or sought, by you).
If interested, do get back to Me. If not, I wish you a speedy completion of this job, which shouldn't take more than a day or two, if done with focus and heart. :)
Cheers
Din
