Finding my son's higher education expenses

I am 59 years old and currently working in the private sector. I have two sons who are studying. Currently, my wife and two sons live in a rented house in Kandy. I am staying in Colombo and working. My eldest son has been selected for higher education at the University of Colombo and is looking forward to studying from April 2026. But we need to spend at least $200 per month including his accommodation fees and food expenses. Also, we need to set aside another $2000 for him to buy a laptop and other necessary expenses when the campus starts. With all this, he will need about $14,000 to study at the university for 5 years. We are living very hard on my salary. Therefore, I have no way to find the $14,000 needed for my son's expenses. If you can, please help me find this $14,000. If anyone can help me with even $200 per month, it would be a great help to me. God bless everyone.
