well, if you're serious about this, i'd contact the UAE Embassy in your country or your Foreign Office/Ministry for Foreign Affairs, a travel firm can't give you appropriate advices about living there
i work in the travel industry myself (not too long ago i organized a trip for my sister who spent the New Year's Eve there), all i know, if you want to travel there you need a tourist VISA (you need to apply for it still you're at home, usually 3-4 weeks before you're planning to travel there, costs around $50), young ladies cannot travel there alone without an escort, i'm not sure about the age limit though, it's 28 methinks

"The government blocks all web sites that it deems ?offensive? to the ?religious, moral, and cultural values? of the UAE. That?s hard to swallow for a freedom loving American, but I get it. I do not understand, however, why all VOIP access and related web sites are blocked. I guess the government also takes offense to people inexpensively contacting their families back home. You?re welcome to call using the analog service provided by the government-owned telephone monopoly, but it will cost you a whole lot more. So much so, in fact, your frequency of calls will be greatly diminished if you can afford them at all. The government says VOIP is blocked for security reasons, yet even the residents of communist China and North Korea have access to these inexpensive calls."
