Authentic home cooked chennai style biriyani

Hey guys, I’m a passionate home cook from chennai in Kadavanthara who’s been perfecting chennai style biriyani. Want to sell this on weekends, 2-3 days a week upon order basis. Combo includes chicken biriyani, chicken 65, raita, salna and bread halwa. 1. How much would you be willing to pay for this combo? 2. Does a delivery of this biriyani to your doorstep sound exciting? Tips/suggestions welcome.
