Well, try hiring good developers.
Try it again with 10 million bucks.

You will notice, that it is not getting any easier.
Developers are a hard to find breed and they usually get2-5x the money, if they don't do games. So even less developers available on the market.

Long story short:
No amount of suprise money is gonna speed development up. They have a team, they can do x hours a day and if they are lucky they may find another person or two every few months.
