The question was not "where do you guys think I should go" but "do you know more about Iranian clinics" as it appears the OP did some research and has interest in Iran specifically:
Unless you can help him with this, or have an idea where he could search, I don't see the point in making an argument out of the fact that you simply don't know. IMO, the people from the Gulf (who have the money + seek for lower prices + are in geographical proximity), as well as Persian diaspora, would know more than this US and Europe-centered community.
