I have heard from a friend about a Company that does SEO and charge per results only, does the on-page, content etc, charging only for the rankings achieved but has someone here actually used it? I am not sure if I can post the URL here please sorry if its not allowed: carlosmarruffo.Com.

I came to the site and spoken to a guy who sent me a prices table for some keywords I wanted and told me I will have to pay when the keywords reach Top50, Top20... Top10 etc, I would like to know if someone has ever used or heard of these guys and tell me your experience before I use their services, there must be a catch right?

Thanks in advance
