Alternative theraphy site

Hi I need a web content writer for our site which we are about to launch. The site offers a social network platform for practitioners/therapists offering alternative theraphy for customers. A practitioner can have their profile and personal blog, submit articles/remedys etc. The site also offers normal users to search for remedys, information on therapies and also search feature to find local practitioners. The content needs to be SEO friendly, and one that will help the sites ranking in search engines. I need someone who can write content that will make it attractive for people to sign up and also practitioners to know the benefits of web markeing their skills within social networks.
