Is the note from vexnet a negotiable instrument? no, since the note is written as "pay to the order" and not to the company itself. no, since the note is not signed. no, since the payment is contingent on performance of the work. yes, since the date of completion of the work is already set.

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
