Sir namaskar, one suggestion reg. swacch bharat mission, for the adv. campaign, you can select Irfan khan, he expresses more while speaking less. An idea for adv would be, one person is eating peanut in verandah but throwing the outer part on road, actor goes to him, eat peanuts but instead of throwing it on road, he keeps it in his pocket, 1st person surprised seeing him doing so and then actor says hum apna ghar ganda nhi karte to ye sadke kyo, ye desh ko bhi swacch rakhna hmari jimmedari hai
