Keywords with highest cost per click

Keywords /CPC
1. conference calling companies $51.66
2. mesothelioma attorneys san diego $51.03
3. boston dui lawyer $50.78
4. mesothelioma patient $50.23
5. purchase structured settlements $50.18

Above list is highest cost per click for the keywords. Do you have any site that focus on above keywords to gain highest payout? The major problems is you compete with other big companies that offer big money for SEO on their site. You are good enough if get listed in first page on Google or Yahoo!.

I'm still configure how I gonna do this, maybe start with less competitive keywords but I will try with the highest CPC keywords first.
