I am a Peruvian citizen by birth - my parents were Chinese and I studied Mechanical Engineering in Scotland - thus I am fluent in English, Chinese and Spanish. Also I can translate technical document from Portuguese to Spanish.
I do translation of commercial and technical documents : contracts, procedures for assemblies and installation of electro-mechanical equipment, technical manuals - mostly for customers in Peru, but I have also some customers in Brasil, Canada and the U.S.A.

I can translate about 2000 - 4000 words per day depending on the nature of the document and also on my personal schedule (as I do some consulting work in engineering).
For the last 10 years, I have translated many large documents for many companies such as Alstom Conversion do Brasil, Alstom Canada, Alstom Power Peru, Sandvik and for several translation agencies.
I normally charge about 8 dollars per page of 230 words - but it can varies (for legal document it can go up to 50 dollars per page, and for Chinese 25 dollars per page)
