Can I get paid to show banners on my side?

Tweet

I have created a website with the name Freeways. In which, I want to include the ways through which we can earn some money from the web. No Scams, cause am providing the links from which I've been paid. Well, I've placed Google adds on my site as well. But I want to show some banners on my site to the advertisers. From which I can be paid to show their banner. Is their any script which can help me provide some space to the advertiser in exchange of money?
