How do you search when the search terms has been dominated by a site?

Currently I am trying to find a website template. And the results seem to be totally dominated by themeforest and its affiliates. I do not like the templates on themeforest so I am looking for an alternative. But google is not helping.

Even if I exclude the themeforest site, its affiliates flood the search results.

How do you all find information in such a case?
