Create a custom font using my handwriting that can randomize the characters being used while typing..

I would like a font that uses my handwriting as the characters. I want the printed font to appear as if it had been hand-written by me. I would like to write the alphabet twenty times, and use each as a separate character set. Letters from each character set would be randomly chosen while typing to make it appear as if the text it had been hand-written by me. Font must be 100% compatible with Microsoft Windows. I'm ready to begin immediately.
