Good day guys/gals

I need some information, I have a very good business idea, something that can(most likely will), change the way we as consumers do business, and how the companies respond to, and acquire new customers.

Where do I go from here?

I have the idea and know whats needed to make it happen, but want to keep the idea safe from scavenger. while collaborating with different fields of specialty, to get an idea of what the start-up capital will be to get the ball rolling.

any help will be appreciated.
