I've found Startpage and its sister site IxQuick to be a good alternative to Google. Same search results with a lot of detritus filtered out, keeps you out of Google's search bubble, and it has built in proxy features.
Instead of Bing, which tracks you for monetization on Microsoft's behalf (though I trust Microsoft with my information more than Google), try DuckDuckGo. It uses Bing as a back end but, like Startpage, proxies the query so your information and identity never hits Microsoft's servers. It's also a much cleaner page code-wise than any other search engine I've seen. It often comes up with more relevant results than Startpage; I find myself often searching both for the same subject so I don't miss what I'm looking for.
