Virtual Assistant who Speaks PHP/SQL SEO and possibly iPhone

My company is expanding to the Middle East, and we need a virtual assistant in UAE or Egypt who can talk with clients about new and ongoing projects. Must have experience in PHP, MySQL, iPhone app development, and Linux. We would pay you on an hourly basis, when you are interacting with clients, then perhaps involve you for development, depending upon the client's needs and your capabilities. The rates would be different, depending upon the functions you perform. $8-$10 for simply responding to client inquiries, conversing with them to determine project needs/goals. A different rate for project management, and a different rate for development (if we enlist your services for development). This would be an ongoing relationship with us, but would not be full-time employment. It would be incident/project-based. Note, the hourly rate is ONLY for communication with client. Once you are involved in development of project, or project-management, we can negotiate a different rate. Must speak both English and professional Standard Arabic (preferably UAE, Egyptian, or Lebanese). We will not accept candidates who are not in the Middle East, or are not Arab. Fluency in Turkish or Persian is a plus. I would create a virtual telephone number that would forward to you.
