السلام عليكم ورحمة الله
I read your offer word by word, and I see that you seek someone to do voice over in Saudi Arabia dialect, it is my pleasure to work with you since I am native Arabic and I was living there for long time so it is easily to make your job
I would like to indicate that I previously did a job similar to yours
I am available right now and I am waiting your response to talk more about details.
Looking forward to work with you.
Regards,
Ahmed
