I want to buy a cow for milk

For milk, choose a dairy cow like Sahiwal, Gir, HF cross, or Jersey cross. First milk her in your presence, then do a CMT test on all four quarters, check the lactation month, and verify age and body condition. If you want fifteen litres or more every day, one cow will not stay at peak all year, so plan two cows with staggered calvings. For any cow above fifty thousand rupees, take a Pashumitra or vet with you before paying.
