Hi
I can do this. I am a developer and seo specialist having previously worked for a large e-retailer before leaving to work for myself.
I will need access to your source code and details of the keywords/search terms that are important to your business.
After that is done, I will modify your content (And your URLs if necessary), before going ahead with a link building programme.
I'm new to Freelancer.com, but not to SEO.
Kind Regards,
WIll
