Make my dream come true.

I am a 29-year-old poor young man. I currently work as a laborer in a tire factory called Ferntino. I earn a salary of about 156 USD per month. Only my mother and I are at home. My father died. My mother is old and it is difficult for her to work now. My mother and I live on the salary I earn from working. The salary I earn from working is used to feed my mother and me. I walk about 5 kilometers to work every day and light a torch at around 4 in the morning. I come home on foot at night after work. So my biggest dream is to buy a bike someday. The salary I earn is used for household chores. So how convenient it would be for me if I had a bike, so buying a bike has become a dream for me. I live in Sri Lanka. Here, a bike can usually be bought for about 1500 USD. So if there is anyone who can make this dream of mine come true, please help me.
