Hi there! Can anyone tell me is there any good profit making business that I can do in Singapore?

My hubby is currently out of job and would like to go into some small business. But we realise business is so difficult to make good profit margins in Singapore these days. Can anyone help to give some advise please coz my family is going into financial difficulties. As u know nowadays Singaporeans have so much financial burdens/debts, we r also 1 of them! HELP!!
