Content for Arabic Teaching website

I am looking for an expert in teaching the Arabic language with great English writing skills who can create engaging content for a free Arabic language teaching website. The content could be a series of blog posts for each level. The content needs to be in the form of written lesson plans, starting from the beginner level along with audio if possible. I'm flexible as to what topics will be included, so I am open to suggestions.
Please check the website and let me know your detailed plan along with the cost as this is an ongoing job:
