Adwords Campaign management

Hello there, We need someone to work on a very specific task on one of our PPC campaigns. PLEASE READ. We need to reduce the minimum cost per click from $0.40 to $0.09 to make the campaign profitable. We know the landing page works, We know the keywords work because...it is only ONE keyword. And a very targeted one (it's not just weigth loss).The landing page is optimized, as well the URL and ad copy. You won't have any useless research to do about findind/testing new keywords. The campaign is already making sales. The ONE thing you need to achieve is "just" reducing the cpc for us. The current QS for that particular keyword is "only" 7 and we believe that if you manage to raise it to 9, the cpc will be lower as well. You may have to slightly tweak the landing page meta tag as well as the ad copy and daily bids. If you are confident that you can succeed in achieving that specific goal of lowering our CPC within a short period of time (and maintaining a high CTR of course), please contact me. Only experts or Google certified may apply. Possibility to work on more other campaigns in the future if we are happy with your results. Regards, Francky
