Translation is somewhere between a science and an art. A professional translator translates between 200 and 800 words an hour depending on the difficulty of the text and the translator's personal experience in the subject area of the text. Use 200 words/hour as an estimate when budgeting time for translation.
Usually, no volume discounts are given for translation services. The first 200 words take as long as the last.
Translation is not just looking up words
in dictionaries and replacing the source words with appropriate
target words in a text. The Portuguese/English language combination
is poorly served in terms of dictionaries, and translators must
develop special glossaries for each project by researching the subject
area. This is also an area where you can help us do a better job!
Provide us with similar texts in one or both languages to guide
our research efforts.
