The excess words in meta description doesn't bring up the negative effect, instead the search engines will knock down the extra characters while considering the site to result for the search query.

Sure! Whilst you have a small amount of traffic, it's the quality that counts. Work on general optimisation of the website, get some decent content on there to extend visibility and maybe look at affiliate stuff. You could look at selling banner space for a fixed sum too
