any good electrician will charge a lot....
i can recommend you Mr. Safdar in Sultan ka Khu...03005131953...
go to him, if you want to clear up the mess of your wiring and make it super clean...he is a master of swaps
you can give him my reference, my name is Jahangir Amin
but remember, the quality of work is directly proportional to the amount of money you pay to an electrician.
