I have just came across some really high paying keywords if anyone wants them. I am selling them for $5. There are 73 keywords ranging from the values of $1.35 to $30.32 CPC. Here is a screenshot for every who does not believe me.
You might have better luck on ebay. We are aware of https://adwords.google.com/select/KeywordToolExternal and words such as law, cancer, mesothelioma, marketing, etc......but good luck.
