Seeking to collaborate with native speakers who have a strong command over the Arabic language to handle translation(magazine,posters)for our upcoming event

Hello everyone we are having an event coming up which many cultures and backgrounds will be displayed, so we are in need of someone who has a strong command over the Arabic native language to translate handouts,magazines, posters from English to Arabic.
We will need an original native speaker for this project, because we want a good quality human translation, and translator should be very familiar with the computer operating system.
We hope that here from you, only original Arabic speakers should place bids.
Thank you.
