I would say get some advertising and employ a development team.

Of course 1 million pages a month is 5500 visitors a day viewing 5 to 6 pages each. And if it is some kind of a community site (forum blogs ect) visitors will visit a higher number of pages meaning the number of visitors you get is less per day.

But definitely you could make some advertising money with it. And then pay a small team to make what you need.
