Budget coffee maker for a small office under ₹8000

What’s the best one-click coffee maker for a small office? My dad needs one for clients, as he's used to instant coffee with milk (like Nescafe Gold or Bru), and so are most of his clients. Currently, an office worker heats milk and makes coffee, but it’s time-consuming, and he’s better at making chai than coffee. We need a machine that can quickly make cappuccinos or similar milk-based coffee with one click.
