Help my family

Hi, I am a school student trying to help my mum with the household expenses. She is the sole breadwinner in my family and have to support 4 schooling children. I want to raise enough money to open a small business of my own, hopefully a shop so that I can help my family lead a better life. I've been working part time while schooling and trying to save up as much as I can, but within 2 years, I've only managed to save up less than $1k. Money is really an issue with me and my family. Hope I can raise enough fund to open a small business. I aspire to help others also who are in the same situation as me when I become successful one day.
