Hassen, where are u man?? we need sponsors. nottoknow, i believe that u don't face any problems with govt approvals. Artists can come on tourist visas. Only thing is they need to be sponsored by the sponsors over here. One of our friend Rayyz can also help u on organizing events. His website is www.e4u.name.qa his org recently organized DJ Suketu show successfully.

regarding indian singers, i would suggest go for sonu nighum. he can get u the maximum crowed i believe.
