Way to Survey-Way to make money at home, paid surveys

More and more 2 of my sites have been generating larger and larger hits..I project by June of this year I will have about 750,000 bi-weekly.

I run 2 servers from my house, and have not started any advertising…how do you make money off advertising?

I dont even know where to begin.
I do this webiste for fun, and I just lost my job, so I think I can earn money.

Can I?
How?

I am really in the need of money. I just got laid off and have very little money in the savings. I do not have too much debt, but a little. I want to know what I can do to make a little extra money in the stock market every month and perhaps some good stocks to invest in. I think I have already made a mistake investing in Citigroup.
