need SEO professional to rank niche websites

i am looking for an absolute SEO pro who knows anything how to rank for different keywords and build backlinks around that. i don´t want just a blackhat spammer which brings me backlinks that hurt more then it helps to rank. i build niche websites around different keywords with unique content. your job is to rank for that keywords. i am NOT looking for linkboosts of spam. i am looking for 100% whitehat SEO that helps my sites rank long term well. i don´t want to loose my adsense account cause of any stupid techniques or something like that! today google made many changes and it is not easy to rank. i am building niche websites with unique content for adsense income and need a long term relationship to an SEO expert who can rank my websites step by step (month for month). i will only pay as soon as i see my sites ranking in google search engine. do NOT try to send me shitty traffic or bulk traffic to receive any payment! - 100% whitehat SEO only. - only SEO experts that are able to wait for payment until we see my sites starting to rank - only SEO experts that want to earn money on a monthly basis on a longterm relationship this bid should be for the first site only.
