I need a professional Search Engine Optimisation person

I have a small website design and search engine optimisation company. I outsourced the SEO to a Uk company but did not achieve any results for my clients waste management company, also Uk based.

I am looking for a professional Individual or company to replace this service and achieve noticeable results for my clients waste management website through on and off site SEO, social media, link building, article and press releases etc.

This is an ongoing opportunity for a monthly fee and could lead to further work in the future.
