Taking care of my elderly mother

I am 58 years old and I work a small job. I have two children, a wife and a mother. We live in a rented house in the Kandy area. Our mother is now 83 years old. She is so weak that she cannot even do her own work. We need to dedicate ourselves to her and provide her with the facilities she needs. The biggest problem we have is that we do not have a house of our own. There are no facilities to take care of an old person in the house where we live. We all live very hard. We would like to give her the necessary facilities in her last days and keep her happy, so we need a house of our own. It takes at least 70,000 dollars to build a house with normal facilities in Sri Lanka. But we are struggling to live with my salary. We have a small piece of land of our own in the Kandy area. If we build a house with the necessary facilities on it, we can make our mother happy and live well. Dear Sirs, if you can, please help us build a house and take care of our mother through this project. God bless you all.
