You won't find a better person for this job.
I am a native, bilingual Arabic and English speaker. My father is Palestinian and mother Lebanese and as you know, the Levant dialect (Lebanese, Palestinian, Syrian) is very very different than Gulf or any other Arab region.
I've seen your bidders and none have my profile which is what you need. And especially when it comes to phrases, you need a Levant dialect and nothing else since they won't even know the phrases used in Lebanon if they are from the Gulf. They say, "whats up" "how are you" "I am good" in very different ways in the Gulf regions and outside Lebanon so trust me they won't help you at all.
I will send you a sample shortly. We can agree to whatever schedule you want and I am willing to even do more than 200 if you'd like - we can just pro rate it.
By the way I used to teach Arabic as a foreign language as a summer job for years and my mom is an Arabic teacher for foreign kids so you're in good hands - especially if you're looking for anything else.
I've lived in Lebanon, Jordan, Dubai, Saudi and the US so I know the phrases you need to get by in the Middle East.
I also went to Georgetown University and helped people there in Arabic.
