Hello!
This is a good job to do! Of course, I do not speak or write any arabic based languages with left to right writing, but with proper guidance that should not be a problem. I am assuming you already have a After Effects file and you need some altering in it, in which case this can be done very quickly and very similar to the original file. I'll be using CS6 version, so compatibility shouldn't be a problem.
You can check my portfolio to see that I have many different video skills and definetly could do your work with top quality. If you need any more clarifications or examples of my work, feel free to contact me.
Thanks for your consideration!
