Further to what I said about the difficulty of doing this. You would need a team of top class people, at least one of whom has done this stuff before. All would need backgrounds in real time or near real time systems. And they would cost serious money.
You would be dead in the water before you started with a bunch of visual basic hackers. Believe me, I've seen how bad poorly educated and unskilled VB hackers can be.
Unless you have more than what you are telling us, I think the whole thing is crazy.
