Change of alternator, alternator belt and rolls

My Vaneo gives some sound from the alternator & alternator belt. Would like to have the alternator changed and at the same time also the belt and rolls. Since i have access to cheap spare parts directly from Germany i would prefer a garage in Trondheim, where i can bring my own spare parts and pay only for the working time. But if that is not possible, then also offers including parts & work are welcome.
