Car scrap dealers

I want to get my car scrapped. I looked through some car scrap centres on justdial. Are the higher rated ones good? Have any of you in Mysore got your vehicles scrapped at those places? It's far from my residence, but it shouldn't matter if scrap service is good. Does anyone know any other places that's good in your experience? What's the procedure? Also car battery is dead. Should I get a service technician to fix the starting issue and then contact the scrap centre? Or can the scrap dealer transport the dead car in their truck? How should I start?
