I launched a Spanish site http://agrupados.biz which is a search engine for clasified ads in Paraguay. I learned Scala und Apache Lucene this way, now I'm hoping to get it at least covering its hosting costs. The site is up aprox. 3 month now and I had almost no visitors before paying Google.
2 days ago I started a Google AdWords campaign so people may find the site, I spend $2.62 so far and got 95 visitors and even won $0.10 with AdSense. Today I added a PayPal donate button.
Right now I'm trying to use it and I'm getting a lot of errors.
As far as I can see, you need to work on the SEO side: there's a lot that needs to be done on that front. Change your title tags structure, create unique descriptions for each page, build friendly urls, make it easy to be crawled, use a sitemap, add to your links the 'title' attribute.
For a site like yours, you should not spend on adwords. You will lose money.
I hope it helps!
