seo on Spanish Lang page; fix for panda and penguin and the rest of the Zoo

I used to get fair traffic for my sites that brought me in a little from affiliate sales. Now it has dried up. I want to return to what it was before. I would like you to fix the page, Metas, sitemaps,etc, and make sure all the pages that my page links to are good. If you know Panda and Penguin you will be able to help quickly. The site for this project is in Spanish. I will pay a third of your fee when I get your diagnosis and work plan. I will pay another third when my page improves by doubling its traffic over the average for January 2013 (for example from 20 individual visitors to 40). I will pay the final third of your bid amount when my page gets up to what they were before the crash in February 2012. This for real, they used to be around 200 unique visits a day). You should not have trouble as the fixes should be easy. If you take the job I will show your stats for the last year. Here are the stats attached to this project. If the diagnosis and work plan is not satisfactory, I will give you a chance to improve it. If the revision is still unsatisfactory, I will cancel. I am serious and honest. I hope I have the good fortune of finding people to take this jobn who are also serious and honest. I want only legal design tht will not get me penalized in any way. After this I will need work on pay for click campaigns.
