Hello, generally, Arabic is taught with two accents in language schools: Formal "Fus-ha" Arabic, and Egyptian dialect Arabic (most common by far). If you can add both here, I will go ahead and sign up for premium membership. :)
I would rather invest in a Marketing person. A lot of stuff in the language learning space is sold thru content marketing. There are a lot of influencers. And they are very open to test drive stuff like this.
