Hi Emerald,
A single condensed page on your site won't rank well on search engines although it will help visitors who do come across your site but don't understand English very well.
To make your life easier, I would recommend:
- Choose a good content management system that already has good multilingual handling (example: Joomla)
- Set up the right project requirements (example: SEO, site architecture, contact form functionality, etc)
- Then just hire copywriters to translate your content keeping in mind keyword research in Russian / Arabic languages.
A good example of such site (Joomla, JomFish, sh404SEF) is http://www.makeuptouch.eu/
Best,
Ogy
