Beside I'm an Arabic native speaker from Egypt, I blog in both English and Arabic.
I will translate your ebook/book from English to Arabic for just $5 per 500 words. So if your book - for instance - consists of 10,000, the total cost will be $100, which means you have to buy this gig 20 times.
Delivering the final translated project will be determined depending on the size of the book as follow:
1,000 words => 1.5 upto 2 days.
2,000 words => 3 upto 4 days.
3,000 words => 4.5 upto 6 days.
and so on ...
Thanks a lot.
