Hi,
1- I don't really see the point of such a project. The idea is fun though.
2- If you add up the number of pixels and the price for each... Well you are going to be rich guys.
3- I don't think you need such an amount of money.
4- The link to your website doesn't work.
I know that many people are accusing each other of trying to scam the community. I have no proof, maybe you are legit but... I assume this is a fraud.
Though, if it isn't, please take some time to explain what's the point of such a project!
