I don't understand this offer. In my point of view it doesn't make any sense. You could also say: "I will give 1000 BTC for free, if you are a big company and accept Bitcoins".
It is nearly impossible to "convince" a huge company to accept Bitcoins. And even if I'm successful and get a company to accept Bitcoins, why should the company tell anyone that it was me who had the idea for it? In fact, if they get to know that you will pay 1000 Bitcoins, they will just create a fake account and get the money for themselves. Even if I post in this thread that I've asked company xyz to do it, someone else (or a fake account from the company) could show up and say "I asked them 3 days ago! I was first!".
So what's the point?
