Hi. I'm an experienced web programmer, but I'm new on freelancer.com, so I'd be happy to modernize your site, and add the text you need, for $100 and a nice review at the end :)
I work with modern standards (html5, css3, Bootstrap 3, JS libs). It will look modern and up to date. Please note that I don't speak Arabic, so you would have to send me the exact text you need added.
Please, contact me to discuss any further details. Looking forward to your reply,
Alex
