Also you can’t make a profit of 2.5ha of land. If you want to do this for a life you need way more. You also need machines, buildings to store stuff and so on. Do not expect to be able to make it into lifetime farming by investing anything less than a million. Probably more depending on the land prices. Also, as you said, farming is a lot of work with very little money to be made. The only way to be profitable is by either planting special crops, diversifying by doing a lot of different stuff or by simply growing to cut costs by utilising machines etc more. Also, without any prior knowledge, this is doomed to fail.
