you can buy some good ranking sites and earn more money from them or otherwise you can flip them to get more money
You don't have to put all your eggs in one basket. Spread that 10K around and see what project brings you the most success. You could buy sites, develop them and flip them. You could invest in a site that already has a good income and drive more traffic to it. You could develop a piece of software that would make marketers drool at the mouth. There are endless possibilities!

Use the money to learn PPC/PPV. People make a lot of money advertising. Its time to reinvest and learn something new Good luck.
