SEO from Poland, Slovakia, Czech Rep.

Does anyone happen to know a person or a company that could help us with our SEO for the

· Polish
· Slovakian
· Czech

version of our website. It should be a for instance a Polish guy and not someone who just knows a little polish from school or so.

I am really only looking for advice on SEO for our German and English pages. We have our stuff in place here but for the other languages it is a little harder to find the right person/company.

Thanks in advance!
