Anyone know the best way for me to finance my plan for global domination?

My friend and were discussing schemes to conquer the world and we found the planning stages to be quite burdensome. So much to take into consideration! Our ultimate goal is to obtain enough financing to build a weapon capable of deflecting an asteroid to put it on a collision course with the planet Earth. With this technology we could easily hold the entire planet hostage and enslave the entire human race. Any ideas how we could finance this? Thanks, everyone.
