Then pay for it, you said you would but then...
You came here looking for a hefty amount of money without disclosing your idea to the public (which is acceptable)
I shown interest and signed your NDA, nex you aren't satisfied and ask for notarization. I said: your idea, you pay for the costs.
And then all of sudden you need my ID instead of paying notarization costs, asked by you!.
No offense man, but red flags all over the deck My identity is worth tens of thousands of "undisclosed ideas"
