How to get a lot of people come in to my site?

[N.A.Q Vampire]

Hello, I have start my business for a week, but I have low experience about adsense.
How can I get lot of people in my site quick? I can invest around $500 to do that, but I have no idea how to do. I have tried with Google Adsense, but I have not sacrifice with that.
I have heared about wordpress.org, but I don't know how to use that either.
Can anyone show me some way to get people in my site? (I only need around 5,000 for each month >"< please show me how)
Note: I want to get people who actually see and want to read my site, not those who only surfing
thanks middy, but I have not a lot of friend in my facebook & twitter. Actually, I only have around 70 people @@
