Have you tried ASD?
It doesn't cost anything. You join for free and you can have your website up for at least 10 days. You get credits for surfing 24 sites a day that you can apply to your own site. You surf 1 site, you website will displayed another time.
They do sell ad packages as well for as little as $10. If you do the daily surfing you can earn the value of your ad package back and then some. http://asdcashgenerator.com/?ref=56368
Another option is 1 on 40. I can't confirm this works yet, but it's free and worth a try. They are meant to be able to get your website to No 1 on google, yahoo and 38 other search engines. http://www.1on40.com/791294584
Hope this helps. I found all these sites while trying ways to expand my businesses also. Good luck!
