58 years old man need help to start a shop

I am 58 years old man. From the age of 16 I am doing hard work to earn for my bread and butter. Since last 6 years I am unable to do any hard work due to an accident and really struggling a lot to earn for my food and accommodation. If I can get about 2500 US$ I can start a small shop from which I can earn till the end of my life. Please help
