165768 Pagerank SEO

Hello, I have a site called www . aukcion . lt , I am in first pages of google in keywords "aukcionas", "aukcionai" (auction in lithuanian speak), but the problem is that my pagerank is 0 , I need to increase this pagerank to 5 or more. Also I don't need black seo and don't want to get penalty from google, if I see that you are using black seo, I won't pay you. Escrow payment, need real SEO specialist. Thanks and happy bidding.
