Translation of text into Arabic, Japanese and traditional Chinese (mandarin)

I am creating an authentication card to go with a new watch brand.

I need the following text to be translated:

'Thank you for purchasing an authentic MORRIS RICHARDSON WATCH product'

Please note 'MORRIS RICHARDSON WATCH' is to stay in English and not to be translated.

I require it to be translated into the following languages:

1) Traditional Chinese (Mandarin)

2) Japanese

3) Arabic

I require an expert for each of the above languages to ensure the translation is 100% accurate.

Many thanks
