186179 keyword selection

I have 3 sites. 1) I need you to research and pick the best 10 keywords that I should target based on my sites current pagerank and content so that i can acheive #1 or top 3 natural search rankings without doing major work on the sites or building a lot of links but still get a good amount of traffic. 2) Find the top 10 keywords I should target for payper click campaings for the same 3 sits, so I pay minimum per click and get the best targeted customers. PM for the site URLs.
