I want to start my own startup business

Hello Everyone, I am Edward form Bangladesh. I was a web developer for 8 years. now I can't continue my work because never staying front of my desk for my eye problem. when I was stay in front of laptop then I fill some problem with my eye pain.

so now I want to start a startup business with my exiting experience about computer center where people can get service like computer servicing, laptop servicing, buy new and old computer, laptops, accessorize. also people can get more service like web develop training, graphic training , then they can involve their own earning and stable their life.

Now I don't have more money for this startup project. because long days I don't have any job in online. now I am fully jobless, I have a family also, I have two daughters. elder one is reading school, little one is 2 years old. their is no income because so it's really painful to continue with happy family, community. I need more then $500 per month costing only for my family living. but now I am very helpless, no body help me to start my startup business either bank also can't help me for my startup business. now what can I do? I want to do something.

So that I asking some money for my startup business for my better living. I promise when I'll make profit then I'll back all of your's money by any orphanage home to donate again.

Thanks for reading my compliments
