AdSense Optimization for 2 sites.

I need someone to optimize my AdSense ads to increase my earnings, already I have two sites (850 daily visits in average - this is for both sites not the daily visits for each), earnings now are $27/month, please let me know how much can you increase the total monthly earnings in your bid. Sites are: cuentapremium dot com and elitefundteam dot com Note that: Full payment will be made only if I see results or the results are closer to your estimate (No escrow payments or milestone payments will be done), add the word "MyAdSense" to your bid to be considered. Greetings.
