I was searching for some keywords the other day and found a "keyword1 keyword2" phrase with 12000 searches and cpc of 6$. I can buy the keyword1-keyword2.net and org domain. The problem is that "keyword1 keyword2" in G returns 4 milion results and intitle:"keyword1 keyword2" returns 60K results.According to traffic travis it has medium difficulty. My plan is to build a large site with more than 100 pages for it. What do you guys think? should I go for it?
