Hi, I would be interested in working for you long term, your request for top ranking on at least 3 keywords is more than possible, i would provide monthly ranking reports etc as full proof of work undertaken. I will get your website +5 ranking but this takes time to gain organic ranking.
My main worry is that results may not be noticable within 1 week, but i can guarantee a noticable change within 4 weeks.
Within 1 week i will have fully SEO your pages and will then re-submit to all spanish language search engines, proof always supplied.
Thanks again, Steve
