Looking to buy: Second-hand bicycle for daily commute

Looking for a decent used bicycle (gear cycle preferred) for daily commute from Kharadi to EON IT Park — about 3-4 km one way. Budget around ₹3,000-5,000. Doesn't need to be fancy, just mechanically sound with working brakes and gears. If you have one gathering dust in your balcony, I'm interested! Can pick up from anywhere in Kharadi or Chandan Nagar area.
