Obviously something has been lost in the translation.
If you want capital "to invest for a big business" then you need to come up with the "business idea."
No one, who is rational, is going to bankroll you to execute on their business premise.
You are 19. How can you convince anyone that you, personally, can make their dream come true; providing they underwrite (100%) the venture?
Hey, it was worth a try, but as I am the only respondant, you should realize that the try failed.
No one (unless they are a cretin) is going to give you their business plan and the money to advance it.
Damn you're cocky - where are you from?
