I agree with John. there's a lot more to this than just setting up shop in another Country and then getting out of taxes. There's things such as where you are a legal resident, where the money is going, etc. all that are factors. I have no idea how the UAE handles things, but I highly doubt they would let you start a business while being a legal resident of another country and then sending all the money to where you live. Maybe the UAE would allow it, but your country will most definitely expect you to pay taxes on that money going in.
Again, I'm not an expert on this, but I do know that there is a lot more to this than you seem to be aware of. Do some research or hire someone to help you.
