Arabic speaking software developer

We have a Windows/SQL based business application. It is translated into 4 languages We have a couple of potential customers in Saudi and now they want some parts of our product translated into arabic.
I would like a software developer who speaks arabic to help us translate some of our forms into arabic and then review/advise how they look
The person is to visit our offices in White Waltham (near Maidenhead) starting at 09:00 and finishing at 18:00 and work with our developers to translate these forms
you will most probably require a specialist keyboard to do the work. So maybe you need to bring your own laptop
We want to do this in the next 2-4 weeks
if successful this may result in more work
