Marketing and copywritting

About me, copy writing & website content
I am currently going through a rebrand at the moment. my old site is www.elitephysiques.co.uk and my current site is very close to be completion but I am a bit of a dunce when it come to the specifics of online marketing and how to sell myself through copy. This is where you come in...
I need very good marketer/copy writer to review my new website and make the appropriate changes to my copy, my about me page and generally review and sort out all the text on my site to make it incredibly appealing.
I myself am a featured writer through various publications but don't know how to use all my credentials to my own benefit to attract my target market and generate leads.
any aplicants must have a track record/portfolio of clients they have helped and unfortunately I'm likely to only use someone in the UK (the time differences and language and cultural barrier will be a problem)
