Agricultural land

I wish to buy 2-3 acres of agricultural land in outskirts or abit outside lahore city.But the prices i have come across are very high for eg. 30 lakh per acre.I wish to buy land at lower cost even if the place is at 30-45 min drive from lahore city.
Please suggest on what location will be least costly to buy land and set up a farm in surrounding areas of lahore city.
