Where to get double breasted men's suit in Mumbai?

Hi, I need it before 4th March. Budget 7k. Readymade or tailored. Searched youtube but could only find blazer market videos. If you are suggesting to get one stitched then please tell if from where can I buy the fabric and a good tailor who won't mess it up. Please suggest shops which are on western line or harbour line(Dockyard Road - CSMT). Thank you.
