They said if you need funding for an idea you should go to the three F's. Friends, Family and Fools. I would first figure out exactly how much money is needed for you to put this startup into action. After you get that number start coming up with plans to achieve it. You could maybe hold a family meeting and pitch the idea to relatives and see who wants to invest. You can put money aside little by little from your current job to reach your investment goals. You can sell a small version of your product on streets and see and use that to help you startup.
