English to Portuguese translation

Good afternoon! We need a translation of 20,000 words from English to Portuguese. The file is pdf and we need it .doc. This is a collection of articles on Wicca and the occult. We would like the language used to be more suitable for young people (20 to 30 years old) and that the localization be done as well, as the original material was written in the northern hemisphere. Thus, the translator must adapt the phases of the moon, the commemorative periods and the seasons of the year, for example, for Brazil.
