Like everyone has stated before, it will probably be a heck of a lot cheaper and a much better idea to just sell your 6MT and buy a new or slightly used DCT M3. There is no way a local BMW shop or any other shop will have as high quality work as what the car comes from the factory. Does this not make any sense to you?
