I am one of the product specialists for the new Matrox Axio/PPro product, I was doing the main theatre demos at the Matrox booth at NAB. I also have a business called Photage Digital Studios and we specialize in 8mm transfers.
This is a completely professional scanned transfer and depending on the amount of footage you have, could be as little as 10 cents per foot. I have done work for others on the COW. Check my bio, I am one of the forum leaders at the Discreet Edit forum. If you are interested, email me offline larry@sherwoodpost.com. I hope I can help you out, you would be very disappointed trying to shoot film images projected onto a wall.
